NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

NOTE 1: BASIS OF PRESENTATION

The accompanying unaudited consolidated financial statements of DNB Financial Corporation (referred to herein as the "Corporation" or "DNB") and its subsidiary, DNB First, National Association (the "Bank") have been prepared in accordance with the instructions for Form 10-Q and therefore do not include certain information or footnotes necessary for the presentation of financial condition, statement of operations and statement of cash flows required by generally accepted accounting principles. However, in the opinion of management, the consolidated financial statements reflect all adjustments (which consist of normal recurring adjustments) necessary for a fair presentation of the results for the unaudited periods. Prior amounts not affecting net income are reclassified when necessary to conform to current period classifications. The results of operations for the three monthsended March 31, 2013 are not necessarily indicative of the results which may be expected for the entire year.  The consolidated financial statements should be read in conjunction with the Annual Report and report on Form 10-K for the year ended December 31, 2012. 

Subsequent Events-- Management has evaluated events and transactions occurring subsequent to March 31, 2013 for items that should potentially be recognized or disclosed in these Consolidated Financial Statements. The evaluation was conducted through the date these financial statements were issued.

Recent Accounting Pronouncements- In February 2013, the FASB issued ASU 2013-02, 'Comprehensive Income (Topic 220): Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income." The amendments in this ASU require an entity to present (either on the face of the statement where net income is presented or in the notes) the effects on the line items of net income of significant amounts reclassified out of accumulated other comprehensive income. In addition, the amendments require a cross-reference to other disclosures currently required for other reclassification items to be reclassified directly to net income in their entirety in the same reporting period. Companies should apply these amendments for fiscal years, and interim periods within those years, beginning on or after December 15, 2012. The Company has included the required disclosures from ASU 2013-02 in the consolidated financial statements.

NOTE 2: BRANCH PURCHASE

On April 2, 2012, the Bank entered into a Purchase and Assumption Agreement with Capital Bank, National Association, to acquire certain assets and assume certain liabilities of one full-service branch office of Capital Bank located in Boothwyn, Pennsylvania (the "Branch Acquisition").

The Bank consummated the Branch Acquisition on June 11, 2012.  The Bank purchased specified assets of the branch, including personal loans totaling $66,000, real estate, furniture and equipment totaling $670,000 and  assumed approximately $15.9 million of deposits.  The Branch Acquisition includes the payment to Capital Bank of $130,000 or a 0.82%  premium on the deposits, which has been recorded as a core deposit intangible.

As of March 31, 2013, there were five corporate bonds, four U.S. agency obligations, seven collateralized mortgage obligations, twenty-five tax-exempt municipalities, twocertificates of deposit, and five equity securities which were in an unrealized loss position. DNB does not intend to sell these securities and management of DNB does not expect to be required to sell any of these securities prior to a recovery of its cost basis. Management does not believe any individual unrealized loss as of March 31, 2013 represents an other-than-temporary impairment. There were two corporate bonds and five equity securities that were impaired for more than 12 months. DNB reviews its investment portfolio on a quarterly basis judging each investment for other-than-temporary impairment (OTTI). The OTTI analysis focuses on duration and amount by which a security is below book. As of March 31, 2013, the following securities were reviewed:

Corporate Securities The unrealized loss on two investments in the corporate bond portfolio was caused by a number of factors. Some of the bonds have had downgrades since they were purchased. Some of the Corporates have been affected by the market's perception of the impact of sovereign debit holdings and spreads on the financial sector have widened since they were purchased. The book value of the two securities is $2.0 million and the unrealized loss is $29,000 or 1.5%.  Both of the bonds have been impaired for more than twelve months and have a loss less than 10% of the book value. The contractual terms of those investments do not permit the issuer to settle these securities at a price less than the par value of the investments. Based on this analysis and an evaluation of DNB's ability and intent to hold these securities for a reasonable period of time sufficient for each security to increase to DNB's cost, DNB does not intend to sell these securities and it is not more likely than not that DNB will be required to sell the securities before recovery of their cost, DNB does not consider these securities to be other-than-temporarily impaired at March 31, 2013.

Equity securities.  DNB's investment in five marketable equity securities consists primarily of securities in common stock of community banks in Pennsylvania. The unrealized losses on the five securities in the equity securities portfolio were all impaired for more than twelve months. The severity and duration of the impairment are driven by higher collateral losses, wider credit spreads, and changes in interest rates within the financial services sector. DNB evaluated the prospects of all issuers in relation to the severity and duration of the impairment. Based on this analysis and an evaluation of DNB's ability and intent to hold these securities for a reasonable period of time sufficient for each security to increase to DNB's cost, DNB does not intend to sell these securities and it is not more likely than not that DNB will be required to sell the securities before recovery of their cost, DNB does not consider these securities to be other-than-temporarily impaired at March 31, 2013.

The amortized cost and fair value of investment securities as of March 31, 2013, by contractual maturity, are shown below. Actual maturities may differ from contractual maturities because certain securities may be called or prepaid without penalties.

NOTE 6: EARNINGS PER SHARE 

Basic earnings per share ("EPS") is computed based on the weighted average number of common shares outstanding during the period. Diluted EPS is computed using the treasury stock method and reflects the potential dilution that could occur from the exercise of stock options, and warrants and the amortized portion of unvested stock awards. Stock options and unvested stock awards for which the exercise or the grant price exceeds the average market price over the period have an anti-dilutive effect on EPS and, accordingly, are excluded from the calculation. Treasury shares are not deemed outstanding for calculations. There were nooutstanding stock warrants in 2013 and 2012,  128,568 anti-dilutive stock options outstanding, and no anti-dilutive stock awards outstanding at March 31, 2013. There were no anti-dilutive stock warrants outstanding, 148,459 anti-dilutive stock options outstanding, and no anti-dilutive stock awards at March 31, 2012. See Note 9  for a discussion of stock warrants issued and redeemed in conjunction with Preferred shares issued to the U.S. Treasury Department as part of the CPP. The following table sets forth the computation of basic and diluted earnings per share:

NOTE 8: JUNIOR SUBORDINATED DEBENTURES

DNB has two issuances of junior subordinated debentures (the "debentures") as follows. The majority of the proceeds of each issuance were invested in DNB's subsidiary, DNB First, National Association, to increase the Bank's capital levels. The junior subordinated debentures issued in each case qualify as a component of capital for regulatory purposes. DNB Capital Trust I and II are special purpose Delaware business trusts, which are not consolidated.

DNB Capital Trust I

DNB's first issuance of junior subordinated debentures was on July 20, 2001. This issuance of debentures are floating rate and were issued to DNB Capital Trust I, a Delaware business trust in which DNB owns all of the common equity. DNB Capital Trust I issued $5.0 million of floating rate (6 month Libor plus 3.75%, with a cap of 12%) capital preferred securities to a qualified institutional buyer. The proceeds of these securities were used by the Trust, along with DNB's capital contribution, to purchase $5.2 million principal amount of DNB's floating rate junior subordinated debentures. The preferred securities have been redeemable since July 25, 2006 and must be redeemed upon maturity of the debentures on July 25, 2031.

DNB Capital Trust II

DNB's second issuance of junior subordinated debentures was on March 30, 2005. This issuance of debentures are floating rate and were issued to DNB Capital Trust II, a Delaware business trust in which DNB owns all of the common equity. DNB Capital Trust II issued $4.0 million of floating rate (the rate was fixed at 6.56% for the first 5 years and is now adjusting at a rate of 3-month LIBOR plus 1.77%) capital preferred securities. The proceeds of these securities were used by the Trust, along with DNB's capital contribution, to purchase $4.1 million principal amount of DNB's floating rate junior subordinated debentures. The preferred securities have been redeemable since May 23, 2010. The preferred securities must be redeemed upon maturity of the debentures on May 23, 2035.

NOTE 9: STOCK-BASED COMPENSATION

Stock Option Plan

DNB has a Stock Option Plan for employees and directors. Under the plan, options (both qualified and non-qualified) to purchase a maximum of 793,368 (as adjusted for subsequent stock dividends) shares of DNB's common stock could be issued to employees and directors. Under the plan, option exercise prices must equal the fair market value of the shares on the date of option grant and the option exercise period may not exceed ten years. Vesting of options under the plan is determined by the Plan Committee. There were 327,964 shares available for grant at March 31, 2013. All options with the exception of 44,600 options granted on April 23, 2010 and 44,600 options granted on December 12, 2011 are immediately exercisable. DNB expensed $17,000 during the three months ended March 31, 2013 and anticipates additional expense of $25,000 through April 23, 2014 for the options granted on April 23, 2010 and $79,000 through December 12, 2014 for the options granted on December 12, 2011, the dates the options can first be exercised. Stock option activity is indicated below.

Other Stock-Based Compensation

DNB maintains an Incentive Equity and Deferred Compensation Plan (the "Plan"). The Plan provides that up to 243,101 (as adjusted for subsequent stock dividends) shares of common stock may be granted, at the discretion of the Board, to individuals of the Corporation. Shares already granted are issuable on the earlier of three years after the date of the grant or a change in control of DNB if the recipients are then employed by DNB ("Vest Date").  Upon issuance of the shares, resale of the shares is restricted for an additional one year, during which the shares may not be sold, pledged or otherwise disposed of. Prior to the Vest Date and in the event the recipient terminates association with DNB for reasons other than death, disability or change in control, the recipient forfeits all rights to the shares that would otherwise be issued under the grant.

Share awards granted by the Plan were recorded at the date of award based on the market value of shares.  Awards are being amortized to expense over the three-year cliff-vesting period. DNB records compensation expense equal to the value of the shares being amortized.  For the three month period ended March 31, 2013, $40,000  was amortized to expense. For the three month period ended March 31, 2012, $18,000was amortized to expense. As of March 31, 2013,  there was approximately $379,000 in additional compensation that will be recognized over the remaining service period of approximately 1.72 years. At March 31, 2013,  158,354 shares were reserved for future grants under the Plan.

As of March 31, 2013, the Corporation had no material unrecognized tax benefits or accrued interest and penalties. It is the Corporation's policy to account for interest and penalties accrued relative to unrecognized tax benefits as a component of income tax expense.  Federal and state tax years 2009through 2012 were open for examination as of March 31, 2013.

NOTE 11:  FAIR VALUE OF FINANCIAL INSTRUMENTS 

FASB ASC Topic 820, Fair Value Measurements and Disclosures, establishes a fair value hierarchy based on the nature of data inputs for fair value determinations, under which DNB is required to value each asset within its scope using assumptions that market participations would utilize to value that asset. When DNB uses its own assumptions, it is required to disclose additional information about the assumptions used and the effect of the measurement on earnings or the net change in assets for the period.

The three levels of the fair value hierarchy under FASB ASC Topic 820 are as follows:

Level 1 Quoted prices in active markets for identical securities.

Level 2 Quoted prices for similar instruments in active markets; quoted prices for identical or similar instruments in markets that are not active and model derived valuations whose inputs are observable or whose significant value drivers are observable.

Level 3 Instruments whose significant value drivers are unobservable.

A description of the valuation methodologies used for assets measured at fair value is set forth below:

DNB's available-for-sale investment securities, which generally include U.S. government agencies and mortgage backed securities, collateralized mortgage obligations, corporate bonds and equity securities are reported at fair value. These securities are valued by an independent third party ("preparer"). The preparer's evaluations are based on market data. They utilize evaluated pricing models that vary by asset and incorporate available trade, bid and other market information. For securities that do not trade on a daily basis, their evaluated pricing applications apply available information such as benchmarking and matrix pricing. The market inputs normally sought in the evaluation of securities include benchmark yields, reported trades, broker/dealer quotes (only obtained from

market makers or broker/dealers recognized as market participants), issuer spreads, two-sided markets, benchmark securities, bid, offers and reference data. For certain securities additional inputs may be used or some market inputs may not be applicable. Inputs are prioritized differently on any given day based on market conditions.

U.S. Government agencies are evaluated and priced using multi‑dimensional relational models and option adjusted spreads. State and municipal securities are evaluated on a series of matrices including reported trades and material event notices. Mortgage backed securities are evaluated using matrix correlation to treasury or floating index benchmarks, prepayment speeds, monthly payment information and other benchmarks. Other securities are evaluated using a broker-quote based application, including quotes from issuers.

Impaired loans are those loans that the Bank has measured impairment generally based on the fair value of the loan's collateral. Fair value is generally determined based upon independent third-party appraisals of the properties, or discounted cash flows based upon the expected proceeds. These assets are included as Level 3 fair values, based upon the lowest level of input that is significant to the fair value measurements.

OREO assets are adjusted to fair value less estimated selling costs upon transfer of the loans to OREO. Subsequently, OREO assets are carried at the lower of carrying value or fair value. Fair value is based upon independent market prices, appraised values of the collateral or management's estimation of the value of the collateral. There assets are included as Level 3 fair values.

The following table summarizes the assets at March 31, 2013 and December 31, 2012 that are recognized on DNB's balance sheet using fair value measurement determined based on the differing levels of input:

(2) Appraisals may be adjusted by management for qualitative factors and disposal costs. The range and weighted average of disposal costs are presented as a percent of the appraisal.

Impaired loans.  Impaired loans, which are measured for impairment using the fair value of the collateral for collateral dependent loans, had a carrying amount of $15.6 million at March 31, 2013. Of this, $8.5 million had a valuation allowance of $1.7 million and $7.1 million had no valuation allowance as of March 31, 2013. Impaired loans had a carrying amount of $12.3 million at December 31, 2012. Of this, $6.9 million had a valuation allowance of $1.0 million and $5.4 million had no valuation allowance as of December 31, 2012.

Other Real Estate Owned & other repossessed property.  Other real estate owned ("OREO") consists of properties acquired as a result of, or in-lieu-of, foreclosure. Properties or other assets (primarily repossessed assets formerly leased) are classified as OREO and other repossessed property are initially recorded at fair value less cost to sell at the date of foreclosure, establishing a new cost basis. Subsequent to foreclosure, valuations are periodically performed by management and the assets are carried at the lower of carrying value or fair value, less estimated costs to sell. Costs relating to the development or improvement of the assets are capitalized and costs relating to holding the assets are charged to expense. DNB had $1.2million of such assets at March 31, 2013, which consisted of $1.1 million in OREO and $94,000 in other repossessed property. DNB had $1.2 million of such assets at December 31, 2012, which consisted of $1.1 million in OREO and $126,000 in other repossessed property. Subsequent to the repossession of these assets, DNB did not write down the carrying values during the three month period ending March 31, 2013.

DNB's policy is to recognize transfer between levels as of the actual date of the event or change in circumstances that caused the transfer. There were no transfers between Level 1 and 2 for the three months ended March 31, 2013.

Below is management's estimate of the fair value of all financial instruments, whether carried at cost or fair value on the Company's consolidated balance sheet. The carrying amounts and fair values of financial instruments at March  31, 2013 and December 31, 2012 are as follows:

The specific estimation methods and assumptions used can have a substantial impact on the resulting fair values of financial instruments. Following is a brief summary of the significant assumptions, methods, and estimates used in estimating fair value.

Limitations  Fair value estimates are made at a specific point in time, based on relevant market information about the financial instrument. These estimates do not reflect any premium or discount that could result from offering for sale at one time DNB's entire holdings of a particular financial instrument. Because no market exists for a significant portion of DNB's financial instruments, fair value estimates are based on judgments regarding future expected loss experience, current economic conditions, risk characteristics of various financial instruments, and other factors. These estimates are subjective in nature and involve uncertainties and matters of significant judgment and therefore cannot be determined with precision. Changes in assumptions could significantly affect the estimates.

Cash and Cash Equivalents, Accrued Interest Receivable and Accrued Interest Payable  The carrying amounts for short-term investments (cash and cash equivalents) and accrued interest receivable and payable approximate fair value.

Investment Securities  The fair value of investment securities are determined by an independent third party ("preparer"). The preparer's evaluations are based on market data. They utilize evaluated pricing models that vary by asset and incorporate available trade, bid and other market information. For securities that do not trade on a daily basis, their evaluated pricing applications apply available information such as benchmarking and matrix pricing. The market inputs normally sought in the evaluation of securities include benchmark yields, reported trades, broker/dealer quotes (only obtained from market makers or broker/dealers recognized as market participants), issuer spreads, two-sided markets, benchmark securities, bid, offers and reference data. For certain securities additional inputs may be used or some market inputs may not be applicable. Inputs are prioritized differently on any given day based on market conditions.

U.S. Government agencies are evaluated and priced using multi‑dimensional relational models and option adjusted spreads. State and municipal securities are evaluated on a series of matrices including reported trades and material event notices. Mortgage backed securities are evaluated using matrix correlation to treasury or floating index benchmarks, prepayment speeds, monthly payment information and other benchmarks. Other investments are evaluated using a broker‑ quote based application, including quotes from issuers. The carrying amount of non-readily marketable equity securities approximates liquidation value.

Restricted Stock  The carrying amount of restricted investment in Federal Home Loan Bank stock, Federal Reserve stock and ACBB stock approximates fair value, and considers the limited marketability of such securities.

Loans  Fair values are estimated for portfolios of loans with similar financial characteristics. Loans are segregated by type such as commercial, commercial mortgages, residential mortgages, consumer and non-accrual loans. The fair value of performing loans is calculated by discounting expected cash flows using an estimated market discount rate. Expected cash flows include both

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

contractual cash flows and prepayments of loan balances. Prepayments on consumer loans were determined using the median of estimates of securities dealers for mortgage-backed investment pools.

The estimated discount rate considers credit and interest rate risk inherent in the loan portfolios and other factors such as liquidity premiums and incremental servicing costs to an investor. Management has made estimates of fair value discount rates that it believes to be reasonable. However, because there is no market for many of these financial instruments, management has no basis to determine whether the fair value presented would be indicative of the value negotiated in an actual sale.

The fair value for non-accrual loans not based on fair value of collateral is derived through a discounted cash flow analysis, which includes the opportunity costs of carrying a non-performing asset. An estimated discount rate was used for these non-accrual loans, based on the probability of loss and the expected time to recovery.

Deposits The fair values disclosed for demand deposits are, by definition, equal to the amount payable on demand at the reporting date (that is, their carrying amounts). The carrying amounts of variable-rate money market accounts, savings accounts, and interest checking accounts approximate their fair values at the reporting date. Fair values for fixed-rate CDs are estimated using a discounted cash flow calculation that applies interest rates currently being offered on certificates to a schedule of aggregated expected monthly maturities on time deposits.

Federal Home Loan Bank of Pittsburgh advances  The fair value of the FHLBP advances is obtained from the FHLB and is calculated by discounting contractual cash flows using an estimated interest rate based on the current rates available for debt of similar remaining maturities and collateral terms.

Repurchase agreements  Fair value approximates the carrying value of such liabilities due to their short-term nature.

Junior subordinated debentures  The fair value for subordinated debentures is calculated using discounted cash flows based upon current market spreads to LIBOR for debt of similar remaining maturities and collateral terms.

Off-balance-sheet Instruments (Disclosed at Cost)  Off-balance-sheet instruments are primarily comprised of loan commitments, which are generally priced at market at the time of funding. Fees on commitments to extend credit and stand-by letters of credit are deemed to be immaterial and these instruments are expected to be settled at face value or expire unused. It is impractical to assign any fair value to these instruments. At March 31, 2013, un-funded loan commitments totaled $77.8 million and stand-by letters of credit totaled $1.9 million. At December 31, 2012, un-funded loan commitments totaled $67.8 million and stand-by letters of credit totaled $2.1 million.

NOTE 12:  STOCKHOLDERS' EQUITY

On January 30, 2009, as part of the Capital Purchase Program ("CPP") of the Emergency Economic Stabilization Act of 2008 administered by the United States Department of the Treasury ("the Treasury"), DNB entered into a Letter Agreement and a Securities Purchase Agreement with the Treasury, pursuant to which the DNB issued and sold on January 30, 2009, and the Treasury purchased for cash on that date (i) 11,750 shares of the Corporation's Fixed Rate Cumulative Perpetual Preferred Stock, Series 2008A, par value $10.00 per share, having a liquidation preference of $1,000 per share ("the CPP shares"), and (ii) a ten-year warrant to purchase up to 186,311 shares of the DNB's common stock, $1.00 par value, at an exercise price of $9.46 per share, for an aggregate purchase price of $11,750,000 in cash. This transaction closed on January 30, 2009. The issuance and sale of these securities was a private placement exempt from registration pursuant to Section 4(2) of the Securities Act of 1933. The Bank provided dividends to the Corporation in connection with the $11,750,000 of Fixed Rate Cumulative Perpetual Preferred Stock sold on January 30, 2009 as part of the CPP.

On August 4, 2011, DNB entered into a Securities Purchase Agreement with the Secretary of the Treasury, pursuant to which the Company issued and sold to the Treasury 13,000 shares of its Non-Cumulative Perpetual Preferred Stock, Series 2011A ("Series 2011A Preferred Stock"), having a liquidation preference of $1,000 per share for aggregate proceeds of $13,000,000.   The Securities Purchase Agreement was entered into, and the Series 2011A Preferred Stock was issued, pursuant to the Treasury's Small Business Lending Fund program ("SBLF"), a $30 billion fund established under the Small Business Jobs Act of 2010, that encourages lending to small businesses by providing capital to qualified community banks with assets of less than $10 billion. Of the $13.0 million in aggregate proceeds, $11,879,000 was used to repurchase all CPP shares ($11,750,000 was paid in principal and $128,900 in accrued, unpaid dividends related to the CPP shares) held by the Treasury as described above. The securities sold in this transaction were exempt from registration under Section 4(2) of the Securities Act of 1933, as amended, as a transaction by DNB not involving a public offering.

The Series 2011A Preferred Stock is entitled to receive non-cumulative dividends payable quarterly, on each January 1, April 1, July 1 and October 1, beginning October 1, 2011.  The dividend rate, which is calculated on the aggregate Liquidation Amount, was initially set at 3.874% per annum, and  was based upon the level of "Qualified Small Business Lending", or "QSBL" (as defined in the Securities Purchase Agreement) originated by the Company's wholly owned national bank subsidiary DNB First, N.A. (the "Bank").  The dividend rate for dividends beyond the initial period are  based upon the "Percentage Change in Qualified Lending" (as defined in the Securities Purchase Agreement) between each dividend period and the "Baseline" QSBL level.  Such dividend rate may vary from 1% per annum to 5% per annum for the second through tenth dividend periods depending on the volume of Qualified Small Business Lending the Bank will originate in future periods, and will be fixed at a rate between 1% per annum to 7% per annum and remain unchanged up to four and one-half years following the funding date (the eleventh through the first half of the nineteenth dividend periods).  Because it is not feasible to predict the volume of Qualified Small Business Lending in future periods, it is not feasible to estimate specific future dividend rates under this formula.  If the Series 2011A Preferred Stock remains outstanding for more than four-and-one-half years, the dividend rate will be fixed at 9%.  Prior to that time, in general, the dividend rate decreases as the level of the Bank's Qualified Small Business Lending increases.  Such dividends are not cumulative, but the Company may only declare and pay dividends on its common stock (or any other equity securities junior to the Series 2011A Preferred Stock) if it has declared and paid dividends for the current dividend period on the Series 2011A Preferred Stock, and will be subject to other restrictions on its ability to repurchase or redeem common stock and other securities.  In addition, if (i) the Company has not timely declared and paid dividends on the Series 2011A Preferred Stock for six dividend periods or more, whether or not consecutive, and (ii) shares of Series 2011A Preferred Stock with an aggregate liquidation preference of at least $13,000,000 are still outstanding, the Treasury (or any successor holder of Series 2011A Preferred Stock) may designate two additional directors to be elected to the Company's Board of Directors. DNB paid an annual rate on the $13.0 million of Series 2011A Preferred Stock of 1.00%, 1.00%  1.00%, 3.90% and 3.80% for the quarters ended March 31, 2013, December 31, 2012, September 30, 2012, June 30, 2012 and March 31, 2012, respectively.

As more completely described in the Certificate of Designation, holders of the Series 2011A Preferred Stock have the right to vote as a separate class on certain matters relating to the rights of holders of Series 2011A Preferred Stock and on certain corporate transactions.  Except with respect to such matters and, if applicable, the election of the additional directors described above, the Series 2011A Preferred Stock does not have voting rights.

The Company may redeem the shares of Series 2011A Preferred Stock, in whole or in part, at any time at a redemption price equal to the sum of the Liquidation Amount per share and the per-share amount of any unpaid dividends for the then-current period, subject to any required prior approval by the Company's primary federal banking regulator.

On September 21, 2011, DNB entered into a letter agreement (the "Warrant Letter Agreement") with the Treasury. Pursuant to the Warrant Letter Agreement, DNB Financial Corporation repurchased from the Treasury the warrant to purchase 186,311 shares of DNB Financial Corporation's common stock issued to Treasury in January 2009 under CPP. DNB Financial Corporation paid a purchase price of $458,000 for the warrant.

DESCRIPTION OF DNB'S BUSINESS AND BUSINESS STRATEGY

DNB Financial Corporation ("DNB" or the "Corporation") is a bank holding company whose bank subsidiary, DNB First, National Association (the "Bank") is a nationally chartered commercial bank with trust powers, and a member of the FDIC. DNB provides a broad range of banking services to individual and corporate customers through its thirteen community offices located throughout Chester and Delaware Counties, Pennsylvania. DNB is a community banking organization that focuses its lending and other services on businesses and consumers in the local market area. DNB funds all these activities with retail and business deposits and borrowings. Through its DNB First InvestmentManagement division, the Bank provides investment management and trust administration services to individuals and non-profit organizations. The Bank and its subsidiary, DNB Investments & Insurance,  provides brokerage, retirement and insurance services.

DNB earns revenues and generates cash flows by lending funds to commercial and consumer customers in its marketplace. DNB generates its largest source of interest income through its lending function. A secondary source of interest income is DNB's investment portfolio, which provides liquidity and cash flows for future lending needs.

In addition to interest earned on loans and investments, DNB earns revenues from fees it charges customers for non-lending services. These services include wealth management and trust services; brokerage and investment services; cash management services; banking and ATM services; as well as safekeeping and other depository services.

To ensure we remain well positioned to meet the growing needs of our customers and communities and to meet the challenges of the 21st century,  we've worked to build awareness of our full-service capabilities and ability to meet the needs of a wide range of customers. This served to not only retain our existing, customer base, but to position ourselves as an attractive financial institution on which younger individuals and families can build their dreams.  To that end, DNB continues to make appropriate investments in all areas of our business, including people, technology, facilities and marketing.

Comprehensive 5-Year Plan.  During the second quarter of 2012, management updated the 5-year strategic plan that was designed to reposition its balance sheet and improve core earnings. Through the plan, management will endeavor to expand its loan portfolio through new originations, increased loan participations, as well as strategic loan and lease receivable purchases. Management also plans to reduce the absolute level of borrowings with cash flows from existing loans and investments as well as from new deposit growth. A discussion on DNB's Key Strategies follows below:

Focus on penetrating existing markets to maximize profitability

Grow loans and diversify the mix

Improve asset quality

Focus on profitable customer segments

Grow and diversify non-interest income, primarily wealth management

28

Focus on reducing DNB's cost of funds by changing DNB's mix of deposits

Focus on cost containment and improving operational efficiencies

Strategic Plan Update.  During the quarter ended March 31, 2013, management focused on reducing DNB'scomposite cost of funds as well as strengthening DNB's net interest margin. The composite cost of funds for the three months ended March 31, 2013 was 0.54% compared to 0.73% in 2012. Management continued to actively manage deposits during 2013 to reduce DNB's cost of funds. Time deposits decreased $3.1 million to $99.2 million at March 31, 2013 compared to $102.3 million at December 31, 2012. Transaction and savings accounts increased $10.2 million during the three months ended March 31, 2013. Positive trends were observed for the three months ended March 31, 2013 in two key business lines that make up total non-interest income: gain on sales of Small Business Administration ("SBA") loans increased $147,000 and wealth management fees increased 22.92% or $58,000 when compared to the same period in 2012. Non-interest expense for the three months ended March 31, 2013 showed a modest increase of 1.67% or $71,000, compared to the same period in 2012, reflecting increases in staffing and occupancy, primarily related to the Boothwyn branch acquisition in 2012. These increases were offset by lower furniture and equipment costs and advertising and marketing costs.  

Management has made a concerted effort to improve the measurement and tracking of business lines and overall corporate performance levels. Improved information systems have increased DNB's ability to track key indicators and enhance corporate performance levels. Better measurement against goals and objectives and increased accountability will be integral in attaining desired loan, deposit and fee income production.

MATERIAL CHALLENGES, RISKS AND OPPORTUNITIES

The following is a summary of material challenges, risks and opportunities DNB has faced during the three-month period ended March 31, 2013:  

Interest Rate Risk Management. Interest rate risk is the exposure to adverse changes in net interest income due to changes in interest rates. DNB considers interest rate risk the predominant risk in terms of its potential impact on earnings.  Interest rate risk can occur for any one or more of the following reasons: (a) assets and liabilities may mature or re-price at different times; (b) short-term or long-term market rates may change by different amounts; or (c) the remaining maturity of various assets or liabilities may shorten or lengthen as interest rates change.

The principal objective of the Bank's interest rate risk management is to evaluate the interest rate risk included in certain on and off-balance sheet accounts, determine the level of risk appropriate given the Bank's business strategy, operating environment, capital and liquidity requirements and performance objectives, and manage the risk consistent with management's approved guidelines. Through such management, DNB seeks to reduce the vulnerability of its operations to changes in interest rates. The Bank's Asset Liability Committee (the "ALCO") is responsible for reviewing the Bank's asset/liability policies and interest rate risk position and making decisions involving asset liability considerations. The ALCO meets on a monthly basis and reports trends and the Bank's interest rate risk position to the Board of Directors.  The extent of the movement of interest rates is an uncertainty that could have a negative impact on the earnings of the Bank.

The largest component of DNB's total income is net interest income, and the majority of DNB's financial instruments are comprised of interest rate-sensitive assets and liabilities with various terms and maturities.  The primary objective of management is to maximize net interest income while minimizing interest rate risk.  Interest rate risk is derived from timing differences in the re-pricing of assets and liabilities, loan prepayments, deposit withdrawals, and differences in lending and funding rates.  The ALCO actively seeks to monitor and control the mix of interest rate-sensitive assets and interest rate-sensitive liabilities. One measure of interest rate risk is net interest income simulation analysis.  The ALCO utilizes simulation analysis, whereby the model estimates the variance in net interest income with a change in interest rates of plus or minus 200 and 300 basis points in addition to four yield curve twists over a twelve-month period.

Liquidity and Market Risk ManagementLiquidity is the ability to meet current and future financial obligations. The Bank further defines liquidity as the ability to respond to deposit outflows as well as maintain flexibility to take advantage of lending and investment opportunities. The Bank's primary sources of funds are operating earnings, deposits, repurchase agreements, principal and interest payments on loans, proceeds from loan sales, principal and interest payments on mortgage backed securities, sales of investment securities, and advances from the FHLB. The Bank uses the funds generated to support its lending and investment activities as well as any other demands for liquidity such as deposit outflows. While maturities and scheduled amortization of loans and securities are predictable sources of funds, deposit flows, mortgage prepayments, loan and security sales and the exercise of call features are greatly influenced by general interest rates, economic conditions and competition.

29

The objective of DNB's asset/liability management function is to maintain consistent growth in net interest income within DNB's policy limits. This objective is accomplished through the management of liquidity and interest rate risk, as well as customer offerings of various loan and deposit products. DNB maintains adequate liquidity to meet daily funding requirements, anticipated deposit withdrawals, or asset opportunities in a timely manner. Liquidity is also necessary to meet obligations during unusual, extraordinary or adverse operating circumstances, while avoiding a significant loss or cost. DNB's foundation for liquidity is a stable deposit base as well as a marketable investment portfolio that provides cash flow through regular maturities or that can be used for collateral to secure funding in an emergency. As part of its liquidity management, DNB maintains assets, which comprise its primary liquidity (Federal funds sold, investments and cash and due from banks, less pledged securities).

Credit Risk Management. DNB defines credit risk as the risk of default by a customer or counter-party.  The objective of DNB's credit risk management strategy is to quantify and manage credit risk on an aggregate portfolio basis as well as to limit the risk of loss resulting from an individual customer default.  Credit risk is managed through a combination of underwriting, documentation and collection standards.  DNB's credit risk management strategy calls for regular credit examinations and quarterly management reviews of large credit exposures and credits that are experiencing credit quality deterioration.  DNB's loan review procedures provide assessments of the quality of underwriting, documentation, risk grading and charge-off procedures, as well as an assessment of the allowance for credit loss reserve analysis process.

Competition.   In addition to the challenges related to the interest rate environment, community banks in Chester and Delaware Counties have been experiencing increased competition from large regional and international banks entering DNB's marketplace through mergers and acquisitions. Competition for loans and deposits may negatively affect DNB's net interest margin. To compensate for the increased competition, DNB, along with other area community banks, has aggressively sought and marketed customers who have been disenfranchised by these mergers. To attract these customers, DNB has introduced new deposit products, such as Mobile Banking, Choice Checking, Credit Cards as well as Executive and employee packages. In addition, DNB has introduced Remote Capture to our commercial customers to expedite their collection of funds.

Deposit Insurance Assessments.  The deposits of the Bank are insured by the FDIC up to the limits set forth under applicable law and are subject to deposit insurance premium assessments. The FDIC imposes a risk based deposit premium assessment system, under which the amount of FDIC assessments paid by an individual insured depository institution, such as the Bank, is based on the level of risk incurred in its activities. The FDIC places a depository institution in one of four risk categories determined by reference to its capital levels and supervisory ratings. In addition, in the case of those institutions in the lowest risk category, the FDIC further determines its assessment rates based on certain specified financial ratios. Pursuant to the Federal Deposit Insurance Act, the FDIC has authority and the responsibility to establish deposit insurance assessments at rates sufficient to maintain the designated reserve ratio of the Deposit Insurance Fund at a level between 1.15% and 1.5% of estimated insured deposits, and to take action to restore the designated reserve ratio to at least 1.15% of estimated insured deposits when it falls below that level. As of June 30, 2008, the designated reserve ratio fell below 1.15%, to 1.01%. On October 7, 2008, the FDIC established a restoration plan which it has updated periodically since then to respond to deteriorating economic conditions. Conditions in the banking industry have continued to deteriorate through 2008 and 2009. According to the FDIC's Quarterly Banking Profile for the Fourth Quarter 2009, as of December 30, 2009 the designated reserve ratio had fallen to (0.39%), down from (0.16%) on September 30, 2009, and 0.36% as of December 31, 2008. The FDIC reports that the December 31, 2009 reserve ratio is the lowest on record for a combined bank and thrift insurance fund. In response to the declining reserve ratio, the FDIC took a series of extraordinary deposit insurance assessment actions during 2009.

Effective as of April 1, 2011, the FDIC adopted changes to its base and risk-based deposit insurance rates. Pursuant to the new rules, a bank's annual assessment base rates were as follows, depending on the bank's risk category:

Initial and Total Base Assessment Rates*

	Risk Category
	Risk Category I	Risk Category II	Risk Category III	Risk Category IV	Large and Highly Complex Institutions
Initial base assessment rate	5-9	14	23	35	5-35
Unsecured debt adjustment**	(4.5)-0	(5)-0	(5)-0	(5)-0	(5)-0
Brokered deposit adjustment		0-10	0-10	0-10	0-10
TOTAL BASE ASSESSMENT RATE	2.5-9	9-24	18-33	30-45	2.5-45

30

*Total base assessment rates do not include the depository institution debt adjustment.

**The unsecured debt adjustment cannot exceed the lesser of 5 basis points or 50 percent of an insured depository institution's initial base assessment rate; thus for example, an insured depository institution with an initial base assessment rate of 5 basis points will have a maximum unsecured debt adjustment of 2.5 basis points and cannot have a total base assessment rate lower than 2.5 basis points.

On November 12, 2009, the FDIC adopted a final rule to require insured institutions to prepay their estimated quarterly risk-based assessments for the fourth quarter of 2009, and for all of 2010, 2011, and 2012. The prepaid assessment was collected on December 30, 2009, along with the institution's regular quarterly risk-based deposit insurance assessment for the third quarter of 2009. For purposes of calculating the prepaid assessment, each institution's assessment rate was its total base assessment rate in effect on September 30, 2009. In calculating the prepayment attributable to 2011 and thereafter, it is calculated using the September 29, 2009 increase in 2011 base assessment rates. In addition, future deposit growth was reflected in the prepayment by assuming that an institution's third quarter 2009 assessment base would be increased quarterly at a 5 percent annual growth rate through the end of 2012. The FDIC began to draw down institutions' prepaid assessments on March 30, 2010, representing payment for the regular quarterly risk-based assessment for the fourth quarter of 2009. In announcing these initiatives, the FDIC stated that, while the prepaid assessment would not immediately affect bank earnings, each institution would record the entire amount of its prepaid assessment as a prepaid expense asset as of December 30, 2009, the date the payment was made and, as of December 31, 2009 and each quarter thereafter, record an expense or charge to earnings for its regular quarterly assessment and an offsetting credit to the prepaid assessment until the asset is exhausted. Once the asset is exhausted, institutions would resume paying and accounting for quarterly deposit insurance assessments as they currently do. The total amount of the Bank's deposit insurance assessment prepayment was $3.1 million.

The Dodd-Frank Wall Street Reform and Consumer Protection Act, or Dodd-Frank Act, that was enacted by Congress on July 15, 2010, and was signed into law by President Obama on July 21, 2010, enacted a number of changes to the federal deposit insurance regime that will affect the deposit insurance assessments the Bank will be obligated to pay in the future.  For example:

-The law permanently raises the federal deposit insurance limit to $250,000 per account ownership.  This change may have the effect of increasing losses to the FDIC insurance fund on future failures of other insured depository institutions.

-The new law makes deposit insurance coverage unlimited in amount for non-interest bearing transaction accounts until December 31, 2012.  This change may also have the effect of increasing losses to the FDIC insurance fund on future failures of other insured depository institutions. Effective January 31, 2013, non-interest bearing transaction accounts will fall under the existing FDIC insurance limit of $250,000 per account ownership.

-The law increases the insurance fund's minimum designated reserve ratio from 1.15 to 1.35, and removes the current 1.50 cap on the reserve ratio. The law gives the FDIC discretion to suspend or limit the declaration or payment of dividends even when the reserve ratio exceeds the minimum designated reserve ratio.

The Dodd-Frank Act expands the base for FDIC insurance assessments, requiring that assessments be based on the average consolidated total assets less tangible equity capital of a financial institution. On February 7, 2011, the FDIC approved a final rule to implement the foregoing provision of the Dodd-Frank Act and to make other changes to the deposit insurance assessment system applicable to insured depository institutions with over $10 billion in assets. Among other things, the final rule eliminates risk categories and the use of long-term debt issuer ratings in calculating risk-based assessments, and instead implements a scorecard method, combining CAMELS ratings and certain forward-looking financial measures to assess the risk an institution poses to the Deposit Insurance Fund. The final rule also revises the assessment rate schedule for large institutions and highly complex institutions to provide assessments ranging from 2.5 to 45 basis points.

Each of these changes may increase the rate of FDIC insurance assessments to maintain or replenish the FDIC's deposit insurance fund.  This could, in turn, raise the Bank's future deposit insurance assessment costs.  On the other hand, the law changes the deposit insurance assessment base so that it will generally be equal to consolidated assets less tangible equity.  This change of the assessment base from an emphasis on deposits to an emphasis on assets is generally considered likely to cause larger banking organizations to pay a disproportionately higher portion of future deposit insurance assessments, which may, correspondingly, lower the level of deposit insurance assessments that smaller community banks such as the Bank may otherwise have to pay in the future. On December 14, 2010, the FDIC issued a final rule setting the insurance fund's designated reserve ratio at 2, which is in excess of the 1.35 minimum designated reserve ratio established by the Dodd-Frank Act. While it is likely that the law will increase the Bank's future deposit insurance assessment costs, the specific amount by which the law's combined changes will affect the Bank's deposit insurance assessment costs is hard to predict, particularly because the law gives the FDIC enhanced discretion to set assessment rate levels.

31

In addition to deposit insurance assessments, banks are subject to assessments to pay the interest on Financing Corporation bonds. The Financing Corporation was created by Congress to issue bonds to finance the resolution of failed thrift institutions. The FDIC sets the Financing Corporation assessment rate every quarter. The current annual Financing Corporation assessment rate is 64 basis points on the deposit insurance assessment base, as defined above, which we anticipate will result in an aggregate estimated FICO assessment payment by the Bank of $36,000 in 2013.

Material Trends and Uncertainties.For the quarter ended March 31, 2013, DNB reported net income of $1.2 million versus $1.1 million for the same period in 2012. During the same respective periods, per share earnings on a fully diluted basis were $0.41 and $0.36. The global and U.S. economies have experienced reduced business activity as a result of disruptions in the financial system during the past four years. The United States, Europe and many other countries across the globe are struggling with too much debt and weaker streams of revenues as a result of recessionary pressures and high unemployment. Overall economic growth continues to be slow and national and regional unemployment rates remain at elevated levels. The risks associated with our business remain acute in periods of slow economic growth and high unemployment. Moreover, financial institutions continue to be affected by a sluggish real estate market and constrained financial markets. While we are continuing to take steps to decrease and limit our exposure to problem loans, we nonetheless retain direct exposure to the residential and commercial real estate markets, and we are affected by these events.

The April 17, 2013 Beige Book indicated that residential builders in the Third Federal Reserve District (the "Third District"), the District where DNB is located, reported modest year-over-year growth rates; however, more new homes were rising from the ground in the first quarter of 2013 that in any year since 2008. Compared with historical patterns, current new construction tends to be smaller, more affordable and more rental units. Residential brokers reported little change in the moderate pace of sales. The existing inventory of homes continues to fall, and investor loans used to convert residential properties to rentals are increasing.

The April 17, 2013 Beige Book indicates that nonresidential real estate has seen little change overall,  maintaining modest growth in leasing activity and slight growth in construction. The Third District's nonresidential real estate contacts are more optimistic, citing increased inquiries, more commitments to decisions, rather that deferrals, and more deals to approve.

The manufacturing sector reported slight increases in overall demand--a pickup since the March 6, 2013 Beige Book. The makers of food products, lumber and wood products, fabricated metals, industrial machinery, electronic equipment and instruments have reported gains since the March 6, 2013 Beige Book. Third District manufacturers have expressed optimism that business conditions will improve during the next six months. However, firms overall have somewhat lowered their expectations of future hiring and their plans for capital spending.

The overall outlook of the Third District's business contacts, many of which have business models similar to DNB's small business clients, remains considerably more optimistic about future business activity. While some uncertainty remains as sequestration unfolds, contacts express greater confidence in the underlying strength of the economy. However, many contacts continue to hold off on their plans to expand capacity and hire more staff.

Although DNB's earnings have been impacted by the general economic conditions, the impact has not been as severe as it has been in many parts of the nation, largely due to a relatively healthier economic climate in the Third Federal Reserve District and specifically Chester County. DNB's franchise spans both Chester and Delaware counties in southeastern Pennsylvania. The majority of loans have been made to businesses and individuals in Chester County and the majority of deposits are from businesses and individuals within the County. According to census data, Chester County's population has grown at approximately 15%, compared to 13% for the nation and 3% for the Commonwealth of Pennsylvania. The median household income in Chester County is $72,288 and the County ranks 14th nationally in disposable income. The unemployment rate for Chester County stood at 5.8% as of March 2013, compared to a Pennsylvania unemployment rate of 7.9% and a national unemployment rate of 7.6%. Traditionally, the unemployment rate has been the lowest in the surrounding five-county area and it ranks among the lowest unemployment rates in the Commonwealth. Chester County has a civilian labor force of 266,100, with manufacturing jobs representing 23.1% of the workforce and retail shopping comprising 13.8% of the total employment. During the last few years, the County has been able to keep most of its major employers, however some of them have downsized in order to remain competitive. Chester County is home to several Fortune 500 companies. Thirteen Chester County employers have 1,000 employees or more. Of these 13 companies, two companies have more than 5,000 employees.

As the U.S. and local economy moves through a period of reduced business activity and historically high unemployment rates, delinquencies will rise as the value of homes decline and DNB's borrowers experience financial difficulty due to corporate downsizing, reduced sales, or other negative events which may impact their ability to meet their contractual loan payments. As a result of continued negative trends in the economy and their impact on our borrowers' ability to repay their loans, DNB made a $180,000 provision for credit losses during the quarter ended March 31, 2013.

These and other factors have impacted our operations. We continue to focus on the consistency and stability of core earnings and balance sheet strength which are critical success factors in today's challenging economic environment.

Regulatory Initiatives Related to Our Industry.The federal government is considering a variety of reforms related to banking and the financial industry including, without limitation, the Dodd-Frank Act.  The Dodd-Frank Act is intended to promote financial stability in the U.S., reduce the risk of bailouts and protect against abusive financial services practices by improving accountability and transparency in the financial system and ending "too big to fail" institutions.  It is the broadest overhaul of the U.S. financial system since the Great Depression, and much of its impact will be determined by the scope and substance of many regulations that will need to be adopted by various regulatory agencies to implement its provisions.  For these reasons, the overall impact on DNB and its subsidiaries remains unknown at this time. 

The Dodd-Frank Act delegates to various federal agencies, including the Consumer Financial Protection Bureau, the task of implementing its many provisions through regulation. Hundreds of new federal regulations, studies and reports addressing all of the major areas of the new law, including the regulation of banks and their holding companies, will be required, ensuring that federal rules and policies in this area will be further developing for months and years to come. Based on the provisions of the Dodd-Frank Act and anticipated implementing regulations, it is highly likely that banks and thrifts as well as their holding companies will be subject to significantly increased regulation and compliance obligations.

The Dodd-Frank Act could require us to make material expenditures, in particular personnel training costs and additional compliance expenses, or otherwise adversely affect our business or financial results.  It could also require us to change certain of our business practices, adversely affect our ability to pursue business opportunities we might otherwise consider engaging in, cause business disruptions and/or have other impacts that are as-of-yet unknown to DNB and the Bank.  Failure to comply with these laws or regulations, even if inadvertent, could result in negative publicity, fines or additional licensing expenses, any of which could have an adverse effect on our cash flow and results of operations.  For example, a provision of the Dodd-Frank Act is intended to preclude bank holding companies from treating future trust preferred securities issuances as Tier 1 capital for regulatory capital adequacy purposes.  This provision may narrow the number of possible capital raising opportunities DNB and other bank holding companies might have in the future.  Further, the new rules issued by the Consumer Financial Protection Bureau may materially affect the methods and costs of compliance by the Bank in connection with future consumer-related transactions.

New Proposed Capital Rules.On June 7, 2012, the Federal Reserve proposed rules that would substantially amend the regulatory risk-based capital rules applicable to the Corporation and the Bank. The FDIC and the OCC subsequently proposed the rules on June 12, 2012. The proposed rules implement the "Basel III" regulatory capital reforms and changes required by the Dodd-Frank Act. "Basel III" refers to two consultative documents released by the Basel Committee on Banking Supervision in December 2009, the rules text released in December 2010, and loss absorbency rules issued in January 2011, which include significant changes to bank capital, leverage and liquidity requirements. The proposed rules were subject to a comment period that expired on October 22, 2012.

The proposed rules include new risk-based capital and leverage ratios, which were to be phased in from 2013 to 2019 but which have been delayed pending further review of the proposed implementing regulations, and would refine the definition of what constitutes "capital" for purposes of calculating those ratios. The proposed new minimum capital level requirements applicable to the Corporation and the Bank under the proposals would be: (i) a new common equity Tier 1 capital ratio of 4.5%; (ii) a Tier 1 capital ratio of 6% (increased from 4%); (iii) a total capital ratio of 8% (unchanged from current rules); and (iv) a Tier 1 leverage ratio of 4% for all institutions. The proposed rules would also establish a "capital conservation buffer" of 2.5% above the new regulatory minimum capital requirements, which must consist entirely of common equity Tier 1 capital and would result in the following minimum ratios: (i) a common equity Tier 1 capital ratio of 7.0%, (ii) a Tier 1 capital ratio of 8.5%, and (iii) a total capital ratio of 10.5%. The new capital conservation buffer requirement would be phased in beginning in January 2016 at 0.625% of risk-weighted assets and would increase by that amount each year until fully implemented in January 2019. An institution would be subject to limitations on paying dividends, engaging in share repurchases, and paying discretionary bonuses if its capital level falls below the buffer amount. These limitations would establish a maximum percentage of eligible retained income that could be utilized for such actions.

Basel III provided discretion for regulators to impose an additional buffer, the "countercyclical buffer," of up to 2.5% of common equity Tier 1 capital to take into account the macro‑financial environment and periods of excessive credit growth. However, the proposed rules permit the countercyclical buffer to be applied only to "advanced approach banks" (i.e. , banks with $250 billion or more in total assets or $10 billion or more in total foreign exposures), which currently excludes the Corporation and the Bank. The proposed rules also implement revisions and clarifications consistent with Basel III regarding the various components of Tier 1 capital, including common equity, unrealized gains and losses, as well as certain instruments that will no longer qualify as Tier 1 capital, some of which would be phased out over time.

The federal bank regulatory agencies also proposed revisions to the prompt corrective action framework, which is designed to place restrictions on insured depository institutions, including the Bank, if their capital levels begin to show signs of weakness. These revisions would take effect January 1, 2015. Under the prompt corrective action requirements, which are designed to complement the

33

capital conservation buffer, insured depository institutions would be required to meet the following increased capital level requirements in order to qualify as "well capitalized:" (i) a new common equity Tier 1 capital ratio of 6.5%; (ii) a Tier 1 capital ratio of 8% (increased from 6%); (iii) a total capital ratio of 10% (unchanged from current rules); and (iv) a Tier 1 leverage ratio of 5% (increased from 4%).

The proposed rules set forth certain changes for the calculation of risk-weighted assets, which we would be required to utilize beginning January 1, 2015. The standardized approach proposed rule utilizes an increased number of credit risk exposure categories and risk weights, and also addresses: (i) a proposed alternative standard of creditworthiness consistent with Section 939A of the Dodd-Frank Act; (ii) revisions to recognition of credit risk mitigation; (iii) rules for risk weighting of equity exposures and past due loans; (iv) revised capital treatment for derivatives and repo-style transactions; and (v) disclosure requirements for top-tier banking organizations with $50 billion or more in total assets that are not subject to the "advance approach rules" that apply to banks with greater than $250 billion in consolidated assets.

On November 9, 2012, the U.S. federal banking agencies released a joint press release indefinitely delaying the January 1, 2013 implementation date for their proposed rules that would revise and replace the current regulatory capital rules according to Basel III and certain provisions of Dodd-Frank.

Other Material Challenges, Risks and Opportunities. As a financial institution, DNB's earnings are significantly affected by general business and economic conditions.  These conditions include short-term and long-term interest rates, inflation, monetary supply, fluctuations in both debt and equity capital markets, and the strength of the United States economy and local economies in which we operate.  As mentioned above in Material Trends and Uncertainties, the economic downturn, increased unemployment, and other events negatively impact household and/or corporate incomes and could decrease the demand for DNB's loan and non-loan products and services and increase the number of customers who fail to pay interest or principal on their loans.  Geopolitical conditions can also affect DNB's earnings.  Acts or threats of terrorism, actions taken by the United States or other governments in response to acts or threats of terrorism and our military conflicts, could impact business conditions in the United States.

CRITICAL ACCOUNTING POLICIES

The following discussion and analysis of financial condition and results of operations is based upon our consolidated financial statements, which have been prepared in accordance with United States generally accepted accounting principals. Generally accepted accounting principles are complex and require management to apply significant judgment to various accounting, reporting and disclosure matters. Management must use assumptions and estimates to apply these principles where actual measurement is not possible or practical. Actual results may differ from these estimates under different assumptions or conditions.

In management's opinion, the most critical accounting policies and estimates impacting DNB's consolidated financial statements are listed below.  These policies are critical because they are highly dependent upon subjective or complex judgments, assumptions and estimates.  Changes in such estimates may have a significant impact on the financial statements.  For a complete discussion of DNB's significant accounting policies, see the footnotes to the Consolidated Financial Statements included in DNB's 10-K for the year ended December 31, 2012.  

Determination of the allowance for credit losses. Credit loss allowance policies involve significant judgments, estimates and assumptions by management which may have a material impact on the carrying value of net loans and leases and, potentially, on the net income recognized by DNB from period to period.  The allowance for credit losses is based on management's ongoing evaluation of the loan and lease portfolio and reflects an amount considered by management to be its best estimate of the amount necessary to absorb known and inherent losses in the portfolio.  Management considers a variety of factors when establishing the allowance, such as the impact of current economic conditions, diversification of the portfolios, delinquency statistics, results of loan review and related classifications, and historic loss rates.  In addition, certain individual loans which management has identified as problematic are specifically provided for, based upon an evaluation of the borrower's perceived ability to pay, the estimated adequacy of the underlying collateral and other relevant factors.  In addition, regulatory authorities, as an integral part of their examinations, periodically review the allowance for credit losses.  They may require additions to the allowance based upon their judgments about information available to them at the time of examination.  Although provisions have been established and segmented by type of loan, based upon management's assessment of their differing inherent loss characteristics, the entire allowance for credit losses is available to absorb further losses in any category.

Management uses significant estimates to determine the allowance for credit losses.  Because the allowance for credit losses is dependent, to a great extent, on conditions that may be beyond DNB's control, management's estimate of the amount necessary to absorb credit losses and actual credit losses could differ.  DNB's current judgment is that the allowance for credit losses remains appropriate at March 31, 2013.  For a description of DNB's accounting policies in connection with its allowance for credit losses, see, "Allowance for Credit Losses", in Management's Discussion and Analysis.

34

Realization of deferred income tax items.Estimates of deferred tax assets and deferred tax liabilities make up the asset category titled "net deferred taxes".  These estimates involve significant judgments and assumptions by management, which may have a material impact on the carrying value of net deferred tax assets for financial reporting purposes.  Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax basis, as well as operating loss carry forwards.  Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled.  The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date.  A valuation allowance would be established against deferred tax assets when in the judgment of management, it is more likely than not that such deferred tax assets will not become available.  For a more detailed description of these items, refer to Footnote 10 (Federal Income Taxes) to DNB's consolidated financial statements for the year ended December 31, 2012. 

The Footnotes to DNB's most recent Consolidated Financial Statements as set forth in DNB's Annual Report 10-K identify other significant accounting policies used in the development and presentation of its financial statements.  This discussion and analysis, the significant accounting policies, and other financial statement disclosures identify and address key variables and other qualitative and quantitative factors that are necessary for an understanding and evaluation of DNB and its results of operations.

FINANCIAL CONDITION

DNB's total assets were $641.78 million at March 31, 2013 compared to $639.57 million at December 31, 2012.  The $2.21 million increase in total assets was primarily attributable to a $5.54 million increase in loans and leases before allowance for credit losses, offset by a $1.57 million decrease in cash and cash equivalents.

Investment Securities.Investment securities including restricted stock at March 31, 2013 were $203.96 million compared to $204.74 million at December 31, 2012. The $784,000decrease in investment securities was primarily due to $13.39million decrease in other securities, offset by increases of $7.82 million and $4.79 million in U.S. agencies and taxexempt securities, respectively.

Gross Loans and Leases.  DNB's loans and leases increased  $5.54million to $402.03 million at March 31, 2013 compared to $396.49million at December 31, 2012.  Total commercial mortgage and commercial loans increased $5.90 million and consumer loans increased $334,000 while residential loans decreased $651,000.

Deposits.  Deposits were $537.54 million at March 31, 2013 compared to $530.42 million at December 31, 2012.  Deposits increased $7.13million or 1.34% during the three-month period ended March 31, 2013.  Core deposits, which are comprised of demand, NOW, money markets and savings accounts, increased by $10.20million while time deposits decreased by $3.08 million. 

Borrowings.Borrowings were $41.66 million at March 31, 2013 compared to $46.86 million at December 31, 2012.  The decrease of $5.20million or 11.11% was primarily due to a $10.00 million decrease in FHLB advances, offset by a $4.80 million increase in repurchase agreements.

Stockholders' Equity.Stockholders' equity was $57.70 million at March 31, 2013 compared to $56.71 million at December 31, 2012. The increase in stockholders' equity was primarily a result of year-to-date earnings of $1.2 million and a $105,000 adjustment to treasury stock for the sale of treasury shares to DNB's401(k) and deferred compensation plans. These additions to stockholders equity were partially offset by $191,000 of dividends paid on DNB's common stock and $32,000 of dividends paid on DNB's Non-Cumulative Perpetual Preferred Stock, Series 2011A. (See Note 12regarding DNB's participation in the Capital Purchase Program ("CPP") of the Emergency Economic Stabilization Act of 2008 and the Treasury's Small Business Lending Fund program ("SBLF"), a $30 billion fund established under the Small Business Jobs Act of 2010.)

RESULTS OF OPERATIONS

SUMMARY

Net income for the three-month period ended March 31, 2013 was $1.18 million compared to $1.10 million for the same period in 2012.  Diluted earnings per share for the three-month period ended March 31, 2013 was $0.41 compared to $0.36 for the same period in 2012.  The $73,000 increase during the three-month period was attributable to a $277,000 increase in non-interest income, a $245,000 decrease in the provision for credit losses, a $191,000 decrease in interest expense and a $16,000 decrease in income tax expense, offset by a $585,000 decrease in interest income and a $71,000 increase in non-interest expense.

35

NET INTEREST INCOME

DNB's earnings performance is primarily dependent upon its level of net interest income, which is the excess of interest income over interest expense.  Interest income includes interest earned on loans, investments and federal funds sold and interest-earning cash, as well as loan fees and dividend income earned on investment securities.  Interest expense includes interest on deposits, Federal Home Loan Bank of Pittsburgh ("FHLBP") advances, repurchase agreements, Federal funds purchased and other borrowings.

Net interest income after provision for credit losses for the three-month period ended March 31, 2013 was $4.79 million compared to $4.94 million for the same period in 2012.  Interest income for the three-month period ended March 31, 2013 was $5.77 million compared to $6.36 million for the same period in 2012.  Interest expense for the three-month period ended March 31, 2013 was $800,000 compared to $991,000  for the same period in 2012.  The composite cost of funds for the three-month period ended March 31, 2013 was 0.54%, compared to 0.73% for the same period in 2012.  The net interest margin for the three-month period ended March 31, 2013 was 3.32% compared to 3.75% for the same period in 2012.  Our provision for credit losses declined from $425,000 during the first quarter of 2012 to $180,000 during the first quarter of 2013, a $245,000 decrease. 

Interest on loans and leases was $4.82 million for the three-month period ended March 31, 2013, compared to $5.51 million for the same period in 2012.  The average balance of loans and leases was $394.79 million with an average yield of 4.94% for the current quarter compared to $405.22 million with an average yield of 5.45% for the same period in 2012. The yield on loans in 2013 was lower than the first quarter of 2012  due to lower rates offered on new loans as well as the reversal of interest income when loans are placed on nonaccrual.

Interest and dividends on investment securities was $938,000 for the three-month periods ended March 31, 2013, compared to $844,000 for the same periods in 2012.  The average balance of investment securities was $193.83 million with a tax equivalent average yield of 2.19% for the current quarter compared to $148.81 million with a tax equivalent average yield of 2.43% for the same period in 2012. 

Interest on deposits was $485,000 for the three-month period ended March 31, 2013, compared to $657,000 for the same period in 2012.  The average balance of deposits was $528.85 million with an average rate of 0.37% for the current quarter compared to $494.84 million with an average rate of 0.53% for the same period in 2012. 

Interest on borrowings was $315,000 for the three-month period ended March 31, 2013, compared to $334,000 for the same period in 2012.  The average balance of borrowings was $49.76 million with an average rate of 2.56% for the current quarter compared to $52.46 million with an average rate of 2.56% for the same period in 2012. 

PROVISION FOR CREDIT LOSSES

To provide for known and inherent losses in the loan and lease portfolios, DNB maintains an allowance for credit losses. Provisions for credit losses are charged against income to increase the allowance when necessary. Loan and lease losses are charged directly against the allowance and recoveries on previously charged-off loans and leases are added to the allowance. In establishing its allowance for credit losses, management considers the size and risk exposure of each segment of the loan and lease portfolio, past loss experience, present indicators of risk such as delinquency rates, levels of non-accruals, the potential for losses in future periods, and other relevant factors. Management's evaluation of criticized and classified loans generally includes reviews of borrowers of $100,000 or greater. Consideration is also given to examinations performed by regulatory agencies, primarily the Office of the Comptroller of the Currency ("OCC").

Management reviews and establishes the adequacy of the allowance for credit losses in accordance with U.S. generally accepted accounting principles, guidance provided by the Securities and Exchange Commission and as prescribed in OCC Bulletin 2006-47. Its methodology for assessing the appropriateness of the allowance consists of several key elements which include: specific allowances for identified impaired loans; and allowances by loan type for pooled homogenous loans. In considering national and local economic trends, we review a variety of information including Federal Reserve publications, general economic statistics, foreclosure rates and housing statistics published by third parties. We believe this improves the measure of inherent loss over a complete economic cycle and reduces the impact for qualitative adjustments. The unallocated portion of the allowance is intended to provide for probable losses not otherwise accounted for in management's other elements of its overall estimate. An unallocated component is maintained to cover uncertainties such as changes in the national and local economy, concentrations of credit, expansion into new markets and other factors that could affect management's estimate of probable losses. The unallocated component of the allowance reflects the margin of imprecision inherent in the underlying assumptions used in the methodologies for estimating specific and general losses in the portfolio.

36

In addition, DNB reviews historical loss experience for the commercial mortgage, commercial, residential mortgage,  lease financing and consumer installment loan pools to determine a historical loss factor. The historical loss factors are then applied to the current portfolio balances to determine the required reserve percentage for each loan pool based on risk rating. Historical losses are segregated into risk-similar groups and a loss ratio is determined for each group over a three year period. The three year average loss ratio by type is then used to calculate the estimated loss based on the current balance of each group. This three year time period is appropriate given DNB's historical level of losses and, more importantly, represents the current economic environment.

This analysis is intended to assess the potential for loss within the loan portfolio and to substantiate the adequacy of the allowance. Should the analysis indicate that the allowance is not adequate, management will recommend a provision expense be made in an amount equal to the shortfall derived. In establishing and reviewing the allowance for adequacy, emphasis has been placed on utilizing the methodology prescribed in OCC Bulletin 2006-47. Management believes that the following factors create a comprehensive system of controls in which management can monitor the quality of the loan portfolio. Consideration has been given to the following factors and variables which may influence the risk of loss within the loan portfolio:

Changes in the nature and volume of the portfolio and in the terms of loans;

Changes in the volume and severity of past due loans, the volume of non-accrual loans, and the volume and severity of adversely classified or graded loans;

The existence and effect of any concentrations of credit, and changes in the level of such concentrations;

Changes in lending policies and procedures, including changes in underwriting standards and collection, charge-off, and recovery practices not considered elsewhere in estimating credit losses;

Changes in the experience, ability, and depth of lending management and other relevant staff;

Changes in the quality of the institution's loan review system;

Changes in international, national, regional, and local economic and business conditions and developments that affect the collectability of the portfolio, including the condition of various market segments;

The effect of other external factors such as competition and legal and regulatory requirements on the level of estimated credit losses in the institution's existing portfolio; and

Changes in the value of underlying collateral for collateral‑dependent loans.

Portfolio risk includes the levels and trends in delinquencies, impaired loans, changes in the loan rating matrix and trends in volume and terms of loans. Management is satisfied with the stability of the past due and non-performing loans and believes there has been no further decline in the quality of the loan portfolio due to any trend in delinquent or adversely classified loans. In determining the adequacy of the allowance, management considered the deterioration of asset quality in DNB's commercial mortgage and residential first mortgage portfolios, which were factors contributing to the increase in the level of allowance during 2012 and 2011. In addition to ordering new appraisals and creating specific reserves on impaired loans, the allowance allocation rates were increased, reflective of delinquency trends which have been caused by continued weakness in the housing markets, falling home equity values, and rising unemployment. New appraisal values we have obtained for existing loans have generally been consistent with trends indicated by Case-Schiller and other indices.

Given the contraction in real estate values, DNB closely monitors the loan to value ratios of all classified assets and requires periodic current appraisals to monitor underlying collateral values. Management also reviews borrower, sponsorship and guarantor's financial strength along with their ability and willingness to provide financial support of their obligations on an immediate and continuing basis.

There was a $180,000 provision made during the three months ended March 31, 2013, compared to $425,000 during the same period in 2012. DNB's percentage of allowance for credit losses to total loans and leases was 1.77%  at March 31, 2013 compared to 1.72% and 1.50% at December 31, 2012 and March 31, 2012, respectively. Net recovery was  $105,000 during the three months ended March 31, 2013.Net charge-offs were $781,000 and $447,000 during the year ended December 31, 2012 and three months ended March 31, 2012, respectively. The percentage of net recovery to toal average loans and leases was 0.03% during the three months ended March 31, 2013. The percentage of net charge-offs to total average loans and leases were 0.21% and 0.11%  during the year ended December 31, 2012 and three months ended March 31, 2012, respectively. Management believes that the allowance for credit losses is adequate, but continues to monitor it along with other performance metrics including those ratios related to non-performing loans and leases. Management is not aware of any potential problem loans, which were accruing and current at March 31,

37

2013, where serious doubt exists as to the ability of the borrower to comply with the present repayment terms and that would result in a significant loss to DNB.Non-performing loans increased $5.8 million during the three month period ended March 31, 2013 due largely to two commercial construction credits totaling $4.3 millionand one commercial mortgage credit for $1.1 million.Three loans which were already criticized assets and closely scrutinized went into collections status.  The bank is well-collateralized and we anticipate moving the properties into foreclosure and off the balance sheet over the next two quarters. Two are cash-flowing properties and management has already received strong interest from potential buyers. The third credit is a lot loan on what we feel is an attractive property. The ratio of the allowance for loan losses as a percentage of loans and leases was 1.77% at March 31, 2013 and 1.72% December 31, 2012and reflects management's estimate of the level of inherent losses in the portfolio, which has been impacted by a recessionary economy, continued high unemployment, a weakened housing market and deterioration in income-producing properties.

We typically establish a general valuation allowance on classified loans which are not impaired. In establishing the general valuation allowance, we segregate these loans by category. The categories used by DNB include "doubtful," "substandard," "special mention," "watch list" and "pass." For commercial mortgage, commercial and construction loans, the determination of the category for each loan is based on periodic reviews of each loan by our lending and credit officers as well as an independent, third-party consultant. The reviews include a consideration of such factors as recent payment history, current financial data, cash flow, financial projections, collateral evaluations, guarantor or sponsorship financial strength and current economic and business conditions. Categories for residential mortgage and consumer loans are determined through a similar review. Classification of a loan within a category is based on identified weaknesses that increase the credit risk of loss on the loan. Each category carries a loss factor for the allowance percentage to be assigned to the loans within that category. The allowance percentage, is determined based on inherent losses associated with each type of lending as determined through consideration of our loss history with each type of loan, trends in credit quality and collateral values, and an evaluation of current economic and business conditions.

We establish a general allowance on non-classified loans to recognize the inherent losses associated with lending activities, but which, unlike specific allowances, have not been allocated to particular problem loans. This general valuation allowance is determined by segregating the loans by loan category and assigning allowance percentages to each category. An evaluation of each category is made to determine the need to further segregate the loans within each category by type. For our residential mortgage and consumer loan portfolios, we identify similar characteristics throughout the portfolio including credit scores, loan-to-value ratios and collateral. For our commercial mortgage and construction loan portfolios, a further analysis is made in which we segregated the loans by type based on the purpose of the loan and the collateral properties securing the loan. Various risk factors for each type of loan are considered, including the impact of general economic and business conditions, collateral value trends, credit quality trends and historical loss experience.

As of March 31, 2013, DNB had $17.5 million of non-performing assets, which included $16.3 million of non-performing or impaired loans and $1.2 million of OREO. This compares to $11.7 million of non-performaing assets at December 31, 2012 which included $10.4 million of non-performing or impaired loans and $1.2 million of OREO.Loans are reviewed for impairment in accordance with FASB ASC 310-10-35. Impaired loans can either be secured or unsecured, not including large groups of smaller balance loans that are collectively evaluated. Impairment is measured by the difference between the loan amount and the present value of the future cash flow discounted at the loan's effective interest rate. Management measures loans for impairment by using the fair value of collateral for collateral dependent loans. In general, management reduces the amount of the appraisal by the estimated cost of acquisition and disposition of the underlying collateral and compares that adjusted value with DNB's carrying value. As part of the general allowance, DNB reserves at the rate of approximately 6% to 10% on non-performing or impaired loans. DNB establishes a specific valuation allowance on impaired loans that have a collateral shortfall, including estimated costs to sell in comparison to the carrying value of the loan. Of the $15.6 million of impaired loans at March 31, 2013, $8.5 million had a valuation allowance of $1.7 million and $7.1 million had no specific allowance above the general allowance as of March 31, 2013.  Of the $12.3 million of impaired loans at December 31, 2012, $6.9 million had a valuation allowance of $1.0 million and $5.4 million had no specific allowance above the general allowance as of December 31, 2012.  For those impaired loans that management determined that no specific valuation allowance was necessary, management has reviewed the present value of the future cash flows or the appraisal for each loan and determined that there is no shortfall in the collateral. During the quarter ended March 31, 2013, we recognized no charge-offs related to impaired loans.  An impaired loan may not represent an expected loss.

We typically order new third-party appraisals or collateral valuations when a loan becomes impaired or is transferred to OREO. This is done within two weeks of a loan becoming impaired or a loan moving to OREO. It generally takes two to eight weeks to receive the appraisals, depending on the type of property being appraised. We recognize any provision or related charge-off within two weeks of receiving the appraisal after the appraisal has been reviewed by DNB. We generally order a new appraisal for all impaired real estate loans having a balance of $100,000 or higher, every twelve months, unless management determines more frequent appraisals are necessary. We use updated valuations when time constraints do not permit a full appraisal process, to reflect rapidly changing market conditions. Because appraisals and updated valuations utilize historical data in reaching valuation conclusions, the appraised or updated value may or may not reflect the actual sales price that we will receive at the time of sale. Management uses the

38

qualitative factor "Changes in the value of underlying collateral for collateral-dependent loans" to calculate any required write-down to mitigate this risk.

Real estate appraisals typically include up to three approaches to value: the sales comparison approach, the income approach (for income-producing property) and the cost approach. Not all appraisals utilize all three approaches to value. Depending on the nature of the collateral and market conditions, the appraiser may emphasize one approach over another in determining the fair value of collateral.

Appraisals may also contain different estimates of value based on the level of occupancy or future improvements. "As-is" valuations represent an estimate of value based on current market conditions with no changes to the collateral's use or condition. "As-stabilized" or "as-completed" valuations assume that the collateral is improved to a stated standard or achieves its highest and best use in terms of occupancy. "As-stabilized" valuations may be subject to a present value adjustment for market conditions or the schedule for improvements.

In connection with the valuation process, we will typically develop an exit strategy for the collateral by assessing overall market conditions, the current condition and use of the asset and its highest and best use. For most income-producing real estate, investors value most highly a stable income stream from the asset; consequently, we conduct a comparative evaluation to determine whether conducting a sale on an "as-is" basis or on an "as-stabilized" basis is most likely to produce the highest net realizable value and compare these values with the costs incurred and the holding period necessary to achieve the "as stabilized" value.

Our estimates of the net realizable value of collateral include a deduction for the expected costs to sell the collateral or such other deductions as deemed appropriate. For most real estate collateral, we apply a seven to ten percent deduction to the value of real estate collateral to determine its expected costs to sell the asset. This estimate generally includes real estate commissions, one year of real estate taxes and miscellaneous repair and closing costs. If we receive a purchase offer that requires unbudgeted repairs, or if the expected holding period for the asset exceeds one year, then we include the additional real estate taxes and repairs or other holding costs in the expected costs to sell the collateral on a case-by-case basis.

NON-INTEREST INCOME

Non-interest income includes service charges on deposit products; fees received in connection with the sale of non-depository products and services, including fiduciary and investment advisory services offered through DNB First InvestmentManagement and Trust; securities brokerage products and services and insurance products and services offered through DNB Investments & Insurance; and other sources of income such as increases in the cash surrender value of Bank Owned Life Insurance ("BOLI"), net gains on sales of investment securities, SBA loans and other real estate owned ("OREO") properties. In addition, DNB receives fees for cash management, remote capture, merchant services, debit cards, safe deposit box rentals and similar activities.

Non-interest income for the three-month period ended March 31, 2013 was $1.20 million compared to $922,000 for the same period in 2012.  The $277,000 increase during the three months ended March 31, 2013 was mainly attributable to an increase of $147,000 in gains on sales of SBA loans, an increase of $59,000 in gains on sale of investments andan increase of $58,000 in DNB Investment Management and Trust.

NON-INTEREST EXPENSE

Non-interest expense for the three-month period ended March 31, 2013 was $4.39 million compared to $4.32 million for the same period in 2012.  This $71,000 increase was primarily due to the Boothwyn branch acquisition in June 2012 which contributed to a $51,000 increase in salary and employee benefits and a $43,000 increase in occupancy.  This was offset by a $35,000 decrease in furniture and equipment and an $18,000 decrease in advertising and marketing.

INCOME TAXES

Income tax expense for the three-month period ended March 31, 2013 was $430,000compared to $446,000 for the same period in 2012. The effective tax rate for the three-month period ended March 31, 2013 was 26.8% compared to 28.8% for the same period in 2012. Income tax expense for each period differs from the amount determined at the statutory rate of 34.0% due to tax-exempt income on loans and investment securities, DNB's ownership of BOLI policies, and tax credits recognized on a low-income housing limited partnership.

ASSET QUALITY

Non-performing assets totaled $17.5 million at March 31, 2013 compared to $11.7 million at December 31, 2012 and $11.2 million at March 31, 2012. Total non-performing assets increased $5.8 million during the threemonths ended March 31, 2013.The

40

$5.8 million increase during the most recent quarter was primarily due tothe addition of five non-accrual loans totalling $5.9 million.As a result of the increase in non-performing loans, the non-performing loans to total loans ratio increased to 4.05% at March 31, 2013, up from 2.63% at December 31, 2012 and 1.79% at March 31, 2012. The non-performing assets to total assets ratio increased to 2.72% at March 31, 2013, up from1.82% at December 31, 2012 and 1.79% at March 31, 2012. The allowance to non-performing loans and leases ratio decreased from 83.8% at March 31, 2012 to 43.8% at March 31, 2013. DNB continues to work diligently to improve asset quality by adhering to strict underwriting standards and improving lending policies and procedures. Non-performing assets have, and will continue to have, an impact on earnings; therefore management intends to continue working aggressively to reduce the level of such assets.

Non-performing assets are comprised of non-accrual loans and leases, loans and leases delinquent over ninety days and still accruing, as well as Other Real Estate Owned ("OREO") and other repossessed assets. Non-accrual loans and leases are loans and leases for which the accrual of interest ceases when the collection of principal or interest payments is determined to be doubtful by management. It is the policy of DNB to discontinue the accrual of interest when principal or interest payments are delinquent 90 days or more (unless the loan principal and interest are determined by management to be fully secured and in the process of collection), or earlier if considered prudent. Interest received on such loans is applied to the principal balance, or may, in some instances, be recognized as income on a cash basis. A non-accrual loan or lease may be restored to accrual status when management expects to collect all contractual principal and interest due and the borrower has demonstrated a sustained period of repayment performance in accordance with the contractual terms. OREO consists of real estate acquired by foreclosure. Other repossessed assets are primarily assets from DNB's commercial lease portfolio that were repossessed. OREO and other repossessed assets are carried at the lower of cost or estimated fair value, less estimated disposition costs. Any significant change in the level of non-performing assets is dependent, to a large extent, on the economic climate within DNB's market area.

DNB's Credit Policy Committee monitors the performance of the loan and lease portfolio to identify potential problem assets on a timely basis. Committee members meet to design, implement and review asset recovery strategies, which serve to maximize the recovery of each troubled asset. As of March 31, 2013, DNB had $10.1million of loans classified as substandard, which, although performing at that date, are believed to require increased supervision and review; and may, depending on the economic environment and other factors, become non-performing assets in future periods. The amount of such loans at December 31, 2012was $14.2 million. The majority of the loans are secured by commercial real estate, with lesser amounts being secured by residential real estate, inventory and receivables.

The following table sets forth those assets that are: (i) placed on non-accrual status, (ii) contractually delinquent by 90 days or more and still accruing, and (iii) OREO as a result of foreclosure or voluntary transfer to DNB as well as other repossessed assets. In addition, the table sets forth DNB's asset quality and allowance coverage ratios at the dates indicated:

LIQUIDITY AND CAPITAL RESOURCES

Management maintains liquidity to meet depositors' needs for funds, to satisfy or fund loan commitments, and for other operating purposes.  DNB's foundation for liquidity is a stable and loyal customer deposit base, cash and cash equivalents, and a marketable investment portfolio that provides periodic cash flow through regular maturities and amortization, or that can be used as collateral to secure funding.  As part of its liquidity management, DNB maintains assets that comprise its primary liquidity, which totaled $122.5 million at March 31, 2013 compared to $132.8 million at December 31, 2012.  Primary liquidity includes investments, Federal funds sold and cash and due from banks, less pledged securities.  DNB also anticipates scheduled payments and prepayments on its loan and mortgage-backed securities portfolios.

In addition, DNB maintains borrowing arrangements with various correspondent banks, the Federal Home Loan Bank of Pittsburgh and the Federal Reserve Bank of Philadelphia to meet short-term liquidity needs.  Through these relationships, DNB has available credit of approximately $190.6 million.  As a member of the FHLB, we are eligible to borrow up to a specific credit limit which is determined by the amount of our residential mortgages, commercial mortgages and other loans that have been pledged as collateral. As of March 31, 2013, our Maximum Borrowing Capacity with the FHLB was $173.6 million. At March 31, 2013, DNB had borrowed $10.0 million and the FHLB had issued letters of credit, on DNB's behalf, totaling $20.0 million against its available credit lines. At March 31, 2013, we also had available $17.0 million of unsecured federal funds lines of credit with other financial institutions as well as $30.0 million of available short or long term funding through the Certificate of Deposit Account Registry Service (CDARS) program. Management believes that DNB has adequate resources to meet its short-term and long-term funding requirements.

On August 5, 2011, Standard & Poor's downgraded the credit rating of the U.S. Government and federal agencies, including the FHLB, from AAA to AA+ , with a negative outlook.  Any future downgrades, in the credit ratings of the U.S. Government and the FHLB could likely increase the borrowing costs of the FHLB and possibly have a negative impact on its operations and long-term performance.  It is possible this could have an adverse effect on the value of the Corporation's investment in FHLB stock. 

42

At March 31, 2013, DNB had $77.8 million in un-funded loan commitments.  Management anticipates these commitments will be funded by means of normal cash flows. Certificates of deposit greater than or equal to $100,000 scheduled to mature in one year or less from March 31, 2013 totaled $35.6 million.  Management believes that the majority of such deposits will be reinvested with DNB and that certificates that are not renewed will be funded by a reduction in cash and cash equivalents or by pay-downs and maturities of loans and investments.

The Corporation and the Bank have each met the definition of "well capitalized" for regulatory purposes on March 31, 2013.  The Bank's capital category is determined for the purposes of applying the bank regulators' "prompt corrective action" regulations and for determining levels of deposit insurance assessments and may not constitute an accurate representation of the Corporation's or the Bank's overall financial condition or prospects. The Corporation's capital exceeds the FRB's minimum leverage ratio requirements for bank holding companies (see additional discussion included in Footnote 17 of DNB's 10-K).

Under federal banking laws and regulations, DNB and the Bank are required to maintain minimum capital as determined by certain regulatory ratios. Capital adequacy for regulatory purposes, and the capital category assigned to an institution by its regulators, may be determinative of an institution's overall financial condition.

The following table summarizes data and ratios pertaining to the Corporation and the Bank's capital structure.

Tier 1 (leverage) capital		66,077	10.5			25,110	4			31,387	5

In addition, the Federal Reserve Bank (the "FRB") leverage ratio rules require bank holding companies to maintain a minimum level of "primary capital" to total assets of 5.5% and a minimum level of "total capital" to total assets of 6%.  For this purpose, (i) "primary capital" includes, among other items, common stock, certain perpetual debt instruments such as eligible Trust preferred securities, contingency and other capital reserves, and the allowance for loan losses, (ii) "total capital" includes, among other things, certain subordinated debt, and "total assets" is increased by the allowance for loan losses.  DNB's primary capital ratio and its total capital ratio are both well in excess of FRB requirements.

REGULATORY MATTERS

Dividends payable to the Corporation by the Bank are subject to certain regulatory limitations. Under normal circumstances, the payment of dividends in any year without regulatory permission is limited to the net profits (as defined for regulatory purposes) for that year, plus the retained net profits for the preceding two calendar years.

ITEM 3 - QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

To measure the impacts of longer-term asset and liability mismatches beyond two years, DNB utilizes an Economic Value of Equity ("EVE") model.  The EVE model measures the potential price risk of equity to changes in interest rates and factors in the optionality included on the balance sheet.  EVE analysis is used to dynamically model the present value of asset and liability cash flows, with rates ranging up or down 200 basis points.  The EVE is likely to be different if rates change.  Results falling outside prescribed ranges may require action by management.  AtMarch 31, 2013 and December 31, 2012, DNB's variance in the EVE as a percentage of assets with an instantaneous and sustained parallel shift of 200 basis points was within its negative 3% guideline, as shown in the table below. The change as a percentage of the present value of equity with a 200 basis point increase atMarch 31, 2013 and December 31, 2012 was within DNB's negative 25% guideline.

(Dollars in thousands)		March 31, 2013						December 31, 2012

Change as % of PV equity				0.4%		(24.3%)				(6.4%)		(17.0%)

ITEM 4- CONTROLS AND PROCEDURES

DNB's Management, with the participation of our Chief Executive Officer and Chief Financial Officer,hasreviewed and evaluated the effectiveness of our disclosure controls and procedures (as defined in Exchange Act Rule 13a-15(e)) as of March 31, 2013, the end of the period covered by this report, in accordance with the requirements of Exchange Act Rule 240.13a-15(b). Based on that evaluation, Management has concluded that DNB's current disclosure controls and procedures are effective.

Management of DNB is responsible for establishing and maintaining adequate internal control over financial reporting for DNB, as such term is defined in Rule 13a-15(f) under the Securities Exchange Act of 1934.  There was no change in DNB's "internal control over financial reporting" (as such term is defined in Rule 13a-15(f) under the Exchange Act) that occurred during the fiscal quarter ended March 31, 2013, that has materially affected, or is reasonably likely to materially affect, DNB's internal control over financial reporting.

Summary of Significant Accounting Policies [Abstract]

BASIS OF PRESENTATION

NOTE 1: BASIS OF PRESENTATION

The accompanying unaudited consolidated financial statements of DNB Financial Corporation (referred to herein as the "Corporation" or "DNB") and its subsidiary, DNB First, National Association (the "Bank") have been prepared in accordance with the instructions for Form 10-Q and therefore do not include certain information or footnotes necessary for the presentation of financial condition, statement of operations and statement of cash flows required by generally accepted accounting principles. However, in the opinion of management, the consolidated financial statements reflect all adjustments (which consist of normal recurring adjustments) necessary for a fair presentation of the results for the unaudited periods. Prior amounts not affecting net income are reclassified when necessary to conform to current period classifications. The results of operations for the three months ended March 31, 2013 are not necessarily indicative of the results which may be expected for the entire year.  The consolidated financial statements should be read in conjunction with the Annual Report and report on Form 10-K for the year ended December 31, 2012. 

Subsequent Events-- Management has evaluated events and transactions occurring subsequent to March 31, 2013 for items that should potentially be recognized or disclosed in these Consolidated Financial Statements. The evaluation was conducted through the date these financial statements were issued.

Recent Accounting Pronouncements- In February 2013, the FASB issued ASU 2013-02, “Comprehensive Income (Topic 220): Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income.” The amendments in this ASU require an entity to present (either on the face of the statement where net income is presented or in the notes) the effects on the line items of net income of significant amounts reclassified out of accumulated other comprehensive income. In addition, the amendments require a cross-reference to other disclosures currently required for other reclassification items to be reclassified directly to net income in their entirety in the same reporting period. Companies should apply these amendments for fiscal years, and interim periods within those years, beginning on or after December 15, 2012. The Company has included the required disclosures from ASU 2013-02 in the consolidated financial statements.

Fair Value of Financial Instruments (Policy)

3 Months Ended

Mar. 31, 2013

Fair Value of Financial Instruments [Abstract]

Fair Value Measurement [Policy Text Block]

FASB ASC Topic 820, Fair Value Measurements and Disclosures, establishes a fair value hierarchy based on the nature of data inputs for fair value determinations, under which DNB is required to value each asset within its scope using assumptions that market participations would utilize to value that asset. When DNB uses its own assumptions, it is required to disclose additional information about the assumptions used and the effect of the measurement on earnings or the net change in assets for the period.

The three levels of the fair value hierarchy under FASB ASC Topic 820 are as follows:

Level 1—Quoted prices in active markets for identical securities.

Level 2—Quoted prices for similar instruments in active markets; quoted prices for identical or similar instruments in markets that are not active and model derived valuations whose inputs are observable or whose significant value drivers are observable.

Level 3—Instruments whose significant value drivers are unobservable.

A description of the valuation methodologies used for assets measured at fair value is set forth below:

DNB’s available-for-sale investment securities, which generally include U.S. government agencies and mortgage backed securities, collateralized mortgage obligations, corporate bonds and equity securities are reported at fair value. These securities are valued by an independent third party (“preparer”). The preparer’s evaluations are based on market data. They utilize evaluated pricing models that vary by asset and incorporate available trade, bid and other market information. For securities that do not trade on a daily basis, their evaluated pricing applications apply available information such as benchmarking and matrix pricing. The market inputs normally sought in the evaluation of securities include benchmark yields, reported trades, broker/dealer quotes (only obtained from market makers or broker/dealers recognized as market participants), issuer spreads, two-sided markets, benchmark securities, bid, offers and reference data. For certain securities additional inputs may be used or some market inputs may not be applicable. Inputs are prioritized differently on any given day based on market conditions.

U.S. Government agencies are evaluated and priced using multi‑dimensional relational models and option adjusted spreads. State and municipal securities are evaluated on a series of matrices including reported trades and material event notices. Mortgage backed securities are evaluated using matrix correlation to treasury or floating index benchmarks, prepayment speeds, monthly payment information and other benchmarks. Other securities are evaluated using a broker-quote based application, including quotes from issuers.

Impaired loans are those loans that the Bank has measured impairment generally based on the fair value of the loan’s collateral. Fair value is generally determined based upon independent third-party appraisals of the properties, or discounted cash flows based upon the expected proceeds. These assets are included as Level 3 fair values, based upon the lowest level of input that is significant to the fair value measurements.

OREO assets are adjusted to fair value less estimated selling costs upon transfer of the loans to OREO. Subsequently, OREO assets are carried at the lower of carrying value or fair value. Fair value is based upon independent market prices, appraised values of the collateral or management’s estimation of the value of the collateral. There assets are included as Level 3 fair values.

Fair Value of Financial Instruments [Policy Text Block]

Limitations  Fair value estimates are made at a specific point in time, based on relevant market information about the financial instrument. These estimates do not reflect any premium or discount that could result from offering for sale at one time DNB’s entire holdings of a particular financial instrument. Because no market exists for a significant portion of DNB’s financial instruments, fair value estimates are based on judgments regarding future expected loss experience, current economic conditions, risk characteristics of various financial instruments, and other factors. These estimates are subjective in nature and involve uncertainties and matters of significant judgment and therefore cannot be determined with precision. Changes in assumptions could significantly affect the estimates.

Cash and Cash Equivalents, Accrued Interest Receivable and Accrued Interest Payable  The carrying amounts for short-term investments (cash and cash equivalents) and accrued interest receivable and payable approximate fair value.

Investment Securities  The fair value of investment securities are determined by an independent third party (“preparer”). The preparer’s evaluations are based on market data. They utilize evaluated pricing models that vary by asset and incorporate available trade, bid and other market information. For securities that do not trade on a daily basis, their evaluated pricing applications apply available information such as benchmarking and matrix pricing. The market inputs normally sought in the evaluation of securities include benchmark yields, reported trades, broker/dealer quotes (only obtained from market makers or broker/dealers recognized as market participants), issuer spreads, two-sided markets, benchmark securities, bid, offers and reference data. For certain securities additional inputs may be used or some market inputs may not be applicable. Inputs are prioritized differently on any given day based on market conditions.

U.S. Government agencies are evaluated and priced using multi‑dimensional relational models and option adjusted spreads. State and municipal securities are evaluated on a series of matrices including reported trades and material event notices. Mortgage backed securities are evaluated using matrix correlation to treasury or floating index benchmarks, prepayment speeds, monthly payment information and other benchmarks. Other investments are evaluated using a broker‑ quote based application, including quotes from issuers. The carrying amount of non-readily marketable equity securities approximates liquidation value.

Restricted Stock  The carrying amount of restricted investment in Federal Home Loan Bank stock, Federal Reserve stock and ACBB stock approximates fair value, and considers the limited marketability of such securities.

Loans  Fair values are estimated for portfolios of loans with similar financial characteristics. Loans are segregated by type such as commercial, commercial mortgages, residential mortgages, consumer and non-accrual loans. The fair value of performing loans is calculated by discounting expected cash flows using an estimated market discount rate. Expected cash flows include both contractual cash flows and prepayments of loan balances. Prepayments on consumer loans were determined using the median of estimates of securities dealers for mortgage-backed investment pools.

The estimated discount rate considers credit and interest rate risk inherent in the loan portfolios and other factors such as liquidity premiums and incremental servicing costs to an investor. Management has made estimates of fair value discount rates that it believes to be reasonable. However, because there is no market for many of these financial instruments, management has no basis to determine whether the fair value presented would be indicative of the value negotiated in an actual sale.

The fair value for non-accrual loans not based on fair value of collateral is derived through a discounted cash flow analysis, which includes the opportunity costs of carrying a non-performing asset. An estimated discount rate was used for these non-accrual loans, based on the probability of loss and the expected time to recovery.

Deposits The fair values disclosed for demand deposits are, by definition, equal to the amount payable on demand at the reporting date (that is, their carrying amounts). The carrying amounts of variable-rate money market accounts, savings accounts, and interest checking accounts approximate their fair values at the reporting date. Fair values for fixed-rate CDs are estimated using a discounted cash flow calculation that applies interest rates currently being offered on certificates to a schedule of aggregated expected monthly maturities on time deposits.

Federal Home Loan Bank of Pittsburgh advances  The fair value of the FHLBP advances is obtained from the FHLB and is calculated by discounting contractual cash flows using an estimated interest rate based on the current rates available for debt of similar remaining maturities and collateral terms.

Repurchase agreements  Fair value approximates the carrying value of such liabilities due to their short-term nature.

Junior subordinated debentures  The fair value for subordinated debentures is calculated using discounted cash flows based upon current market spreads to LIBOR for debt of similar remaining maturities and collateral terms.

Off-balance-sheet Instruments (Disclosed at Cost)  Off-balance-sheet instruments are primarily comprised of loan commitments, which are generally priced at market at the time of funding. Fees on commitments to extend credit and stand-by letters of credit are deemed to be immaterial and these instruments are expected to be settled at face value or expire unused. It is impractical to assign any fair value to these instruments. At March 31, 2013, un-funded loan commitments totaled $77.8 million and stand-by letters of credit totaled $1.9 million. At December 31, 2012, un-funded loan commitments totaled $67.8 million and stand-by letters of credit totaled $2.1 million

Under the plan, options (both qualified and non-qualified) to purchase a maximum of 793,368 (as adjusted for subsequent stock dividends) shares of DNB’s common stock could be issued to employees and directors. Under the plan, option exercise prices must equal the fair market value of the shares on the date of option grant and the option exercise period may not exceed ten years. Vesting of options under the plan is determined by the Plan Committee. There were 327,964 shares available for grant at March 31, 2013. All options with the exception of 44,600 options granted on April 23, 2010 and 44,600 options granted on December 12, 2011 are immediately exercisable. DNB expensed $17,000 during the three months ended March 31, 2013 and anticipates additional expense of $25,000 through April 23, 2014 for the options granted on April 23, 2010 and $79,000 through December 12, 2014 for the options granted on December 12, 2011, the dates the options can first be exercised.

Other Stock-Based Compensation

DNB maintains an Incentive Equity and Deferred Compensation Plan (the "Plan"). The Plan provides that up to 243,101 (as adjusted for subsequent stock dividends) shares of common stock may be granted, at the discretion of the Board, to individuals of the Corporation. Shares already granted are issuable on the earlier of three years after the date of the grant or a change in control of DNB if the recipients are then employed by DNB (“Vest Date”).  Upon issuance of the shares, resale of the shares is restricted for an additional one year, during which the shares may not be sold, pledged or otherwise disposed of. Prior to the Vest Date and in the event the recipient terminates association with DNB for reasons other than death, disability or change in control, the recipient forfeits all rights to the shares that would otherwise be issued under the grant.

Share awards granted by the Plan were recorded at the date of award based on the market value of shares.  Awards are being amortized to expense over the three-year cliff-vesting period. DNB records compensation expense equal to the value of the shares being amortized.  For the three month period ended March 31, 2013, $40,000 was amortized to expense. For the three month period ended March 31, 2012, $18,000 was amortized to expense. As of March 31, 2013, there was approximately $379,000 in additional compensation that will be recognized over the remaining service period of approximately 1.72 years. At March 31, 2013, 158,354 shares were reserved for future grants under the Plan.

As of March 31, 2013, there were five corporate bonds, four U.S. agency obligations, seven collateralized mortgage obligations,twenty-five tax-exempt municipalities, two certificates of deposit, and five equity securities which were in an unrealized loss position. DNB does not intend to sell these securities and management of DNB does not expect to be required to sell any of these securities prior to a recovery of its cost basis. Management does not believe any individual unrealized loss as of March 31, 2013 represents an other-than-temporary impairment. There were two corporate bonds and five equity securities that were impaired for more than 12 months. DNB reviews its investment portfolio on a quarterly basis judging each investment for other-than-temporary impairment (OTTI). The OTTI analysis focuses on duration and amount by which a security is below book. As of March 31, 2013, the following securities were reviewed:

Corporate Securities The unrealized loss on two investments in the corporate bond portfolio was caused by a number of factors. Some of the bonds have had downgrades since they were purchased. Some of the Corporates have been affected by the market's perception of the impact of sovereign debit holdings and spreads on the financial sector have widened since they were purchased. The book value of the two securities is $2.0 million and the unrealized loss is $29,000 or 1.5%. Both of the bonds have been impaired for more than twelve months and have a loss less than 10% of the book value. The contractual terms of those investments do not permit the issuer to settle these securities at a price less than the par value of the investments. Based on this analysis and an evaluation of DNB’s ability and intent to hold these securities for a reasonable period of time sufficient for each security to increase to DNB’s cost, DNB does not intend to sell these securities and it is not more likely than not that DNB will be required to sell the securities before recovery of their cost, DNB does not consider these securities to be other-than-temporarily impaired at March 31, 2013.

Equity securities.  DNB’s investment in five marketable equity securities consists primarily of securities in common stock of community banks in Pennsylvania. The unrealized losses on the five securities in the equity securities portfolio were all impaired for more than twelve months. The severity and duration of the impairment are driven by higher collateral losses, wider credit spreads, and changes in interest rates within the financial services sector. DNB evaluated the prospects of all issuers in relation to the severity and duration of the impairment. Based on this analysis and an evaluation of DNB’s ability and intent to hold these securities for a reasonable period of time sufficient for each security to increase to DNB’s cost, DNB does not intend to sell these securities and it is not more likely than not that DNB will be required to sell the securities before recovery of their cost, DNB does not consider these securities to be other-than-temporarily impaired at March 31, 2013.

The amortized cost and fair value of investment securities as of March 31, 2013, by contractual maturity, are shown below. Actual maturities may differ from contractual maturities because certain securities may be called or prepaid without penalties.

Fair Value of Financial Instruments

Fair Value of Financial Instruments [Abstract]

FAIR VALUE OF FINANCIAL INSTRUMENTS

NOTE 11:  FAIR VALUE OF FINANCIAL INSTRUMENTS 

FASB ASC Topic 820, Fair Value Measurements and Disclosures, establishes a fair value hierarchy based on the nature of data inputs for fair value determinations, under which DNB is required to value each asset within its scope using assumptions that market participations would utilize to value that asset. When DNB uses its own assumptions, it is required to disclose additional information about the assumptions used and the effect of the measurement on earnings or the net change in assets for the period.

The three levels of the fair value hierarchy under FASB ASC Topic 820 are as follows:

Level 1—Quoted prices in active markets for identical securities.

Level 2—Quoted prices for similar instruments in active markets; quoted prices for identical or similar instruments in markets that are not active and model derived valuations whose inputs are observable or whose significant value drivers are observable.

Level 3—Instruments whose significant value drivers are unobservable.

A description of the valuation methodologies used for assets measured at fair value is set forth below:

DNB’s available-for-sale investment securities, which generally include U.S. government agencies and mortgage backed securities, collateralized mortgage obligations, corporate bonds and equity securities are reported at fair value. These securities are valued by an independent third party (“preparer”). The preparer’s evaluations are based on market data. They utilize evaluated pricing models that vary by asset and incorporate available trade, bid and other market information. For securities that do not trade on a daily basis, their evaluated pricing applications apply available information such as benchmarking and matrix pricing. The market inputs normally sought in the evaluation of securities include benchmark yields, reported trades, broker/dealer quotes (only obtained from market makers or broker/dealers recognized as market participants), issuer spreads, two-sided markets, benchmark securities, bid, offers and reference data. For certain securities additional inputs may be used or some market inputs may not be applicable. Inputs are prioritized differently on any given day based on market conditions.

U.S. Government agencies are evaluated and priced using multi‑dimensional relational models and option adjusted spreads. State and municipal securities are evaluated on a series of matrices including reported trades and material event notices. Mortgage backed securities are evaluated using matrix correlation to treasury or floating index benchmarks, prepayment speeds, monthly payment information and other benchmarks. Other securities are evaluated using a broker-quote based application, including quotes from issuers.

Impaired loans are those loans that the Bank has measured impairment generally based on the fair value of the loan’s collateral. Fair value is generally determined based upon independent third-party appraisals of the properties, or discounted cash flows based upon the expected proceeds. These assets are included as Level 3 fair values, based upon the lowest level of input that is significant to the fair value measurements.

OREO assets are adjusted to fair value less estimated selling costs upon transfer of the loans to OREO. Subsequently, OREO assets are carried at the lower of carrying value or fair value. Fair value is based upon independent market prices, appraised values of the collateral or management’s estimation of the value of the collateral. There assets are included as Level 3 fair values.

The following table summarizes the assets at March 31, 2013 and December 31, 2012 that are recognized on DNB’s balance sheet using fair value measurement determined based on the differing levels of input:

The following table presents additional information about assets measured at fair value on a nonrecurring basis and for which DNB has utilized Level 3 inputs to determine fair value:

Quantitative Information about Level 3 Fair Value Measurement
(Dollars in thousands)		Fair Value	Valuation		Range (Weighted

March 31, 2013
Impaired loans- Commercial construction	$	1,864	Appraisal of collateral (1)	Appraisal adj.	0%	to	0%	(0%)
				Disposal costs	-10%	to	-10%	(-10%)

Impaired loans- Residential mortgage	$	267	Appraisal of collateral (1)	Appraisal adj.	-40%	to	-40%	(-40%)
				Disposal costs	-8%	to	-8%	(-8%)

* As of March 31, 2013 there is only 1 loan in the commercial construction and residential mortgage loan types.

(1) Fair value is generally determined through independent appraisals of the underlying collateral, which generally include various level 3 inputs which are not identifiable.

(2) Appraisals may be adjusted by management for qualitative factors and disposal costs. The range and weighted average of disposal costs are presented as a percent of the appraisal.

Impaired loans.  Impaired loans, which are measured for impairment using the fair value of the collateral for collateral dependent loans, had a carrying amount of $15.6 million at March 31, 2013. Of this, $8.5 million had a valuation allowance of $1.7 million and $7.1 million had no valuation allowance as of March 31, 2013. Impaired loans had a carrying amount of $12.3 million at December 31, 2012. Of this, $6.9 million had a valuation allowance of $1.0 million and $5.4 million had no valuation allowance as of December 31, 2012.

Other Real Estate Owned & other repossessed property.  Other real estate owned (“OREO”) consists of properties acquired as a result of, or in-lieu-of, foreclosure. Properties or other assets (primarily repossessed assets formerly leased) are classified as OREO and other repossessed property are initially recorded at fair value less cost to sell at the date of foreclosure, establishing a new cost basis. Subsequent to foreclosure, valuations are periodically performed by management and the assets are carried at the lower of carrying value or fair value, less estimated costs to sell. Costs relating to the development or improvement of the assets are capitalized and costs relating to holding the assets are charged to expense. DNB had $1.2 million of such assets at March 31, 2013, which consisted of $1.1 million in OREO and $94,000 in other repossessed property. DNB had $1.2 million of such assets at December 31, 2012, which consisted of $1.1 million in OREO and $126,000 in other repossessed property. Subsequent to the repossession of these assets, DNB did not write down the carrying values during the three month period ending March 31, 2013.

DNB's policy is to recognize transfer between levels as of the actual date of the event or change in circumstances that caused the transfer. There were no transfers between Level 1 and 2 for the three months ended March 31, 2013.

Below is management’s estimate of the fair value of all financial instruments, whether carried at cost or fair value on the Company’s consolidated balance sheet. The carrying amounts and fair values of financial instruments at March 31, 2013 and December 31, 2012 are as follows:

The specific estimation methods and assumptions used can have a substantial impact on the resulting fair values of financial instruments. Following is a brief summary of the significant assumptions, methods, and estimates used in estimating fair value.

Limitations  Fair value estimates are made at a specific point in time, based on relevant market information about the financial instrument. These estimates do not reflect any premium or discount that could result from offering for sale at one time DNB’s entire holdings of a particular financial instrument. Because no market exists for a significant portion of DNB’s financial instruments, fair value estimates are based on judgments regarding future expected loss experience, current economic conditions, risk characteristics of various financial instruments, and other factors. These estimates are subjective in nature and involve uncertainties and matters of significant judgment and therefore cannot be determined with precision. Changes in assumptions could significantly affect the estimates.

Cash and Cash Equivalents, Accrued Interest Receivable and Accrued Interest Payable  The carrying amounts for short-term investments (cash and cash equivalents) and accrued interest receivable and payable approximate fair value.

Investment Securities  The fair value of investment securities are determined by an independent third party (“preparer”). The preparer’s evaluations are based on market data. They utilize evaluated pricing models that vary by asset and incorporate available trade, bid and other market information. For securities that do not trade on a daily basis, their evaluated pricing applications apply available information such as benchmarking and matrix pricing. The market inputs normally sought in the evaluation of securities include benchmark yields, reported trades, broker/dealer quotes (only obtained from market makers or broker/dealers recognized as market participants), issuer spreads, two-sided markets, benchmark securities, bid, offers and reference data. For certain securities additional inputs may be used or some market inputs may not be applicable. Inputs are prioritized differently on any given day based on market conditions.

U.S. Government agencies are evaluated and priced using multi‑dimensional relational models and option adjusted spreads. State and municipal securities are evaluated on a series of matrices including reported trades and material event notices. Mortgage backed securities are evaluated using matrix correlation to treasury or floating index benchmarks, prepayment speeds, monthly payment information and other benchmarks. Other investments are evaluated using a broker‑ quote based application, including quotes from issuers. The carrying amount of non-readily marketable equity securities approximates liquidation value.

Restricted Stock  The carrying amount of restricted investment in Federal Home Loan Bank stock, Federal Reserve stock and ACBB stock approximates fair value, and considers the limited marketability of such securities.

Loans  Fair values are estimated for portfolios of loans with similar financial characteristics. Loans are segregated by type such as commercial, commercial mortgages, residential mortgages, consumer and non-accrual loans. The fair value of performing loans is calculated by discounting expected cash flows using an estimated market discount rate. Expected cash flows include both contractual cash flows and prepayments of loan balances. Prepayments on consumer loans were determined using the median of estimates of securities dealers for mortgage-backed investment pools.

The estimated discount rate considers credit and interest rate risk inherent in the loan portfolios and other factors such as liquidity premiums and incremental servicing costs to an investor. Management has made estimates of fair value discount rates that it believes to be reasonable. However, because there is no market for many of these financial instruments, management has no basis to determine whether the fair value presented would be indicative of the value negotiated in an actual sale.

The fair value for non-accrual loans not based on fair value of collateral is derived through a discounted cash flow analysis, which includes the opportunity costs of carrying a non-performing asset. An estimated discount rate was used for these non-accrual loans, based on the probability of loss and the expected time to recovery.

Deposits The fair values disclosed for demand deposits are, by definition, equal to the amount payable on demand at the reporting date (that is, their carrying amounts). The carrying amounts of variable-rate money market accounts, savings accounts, and interest checking accounts approximate their fair values at the reporting date. Fair values for fixed-rate CDs are estimated using a discounted cash flow calculation that applies interest rates currently being offered on certificates to a schedule of aggregated expected monthly maturities on time deposits.

Federal Home Loan Bank of Pittsburgh advances  The fair value of the FHLBP advances is obtained from the FHLB and is calculated by discounting contractual cash flows using an estimated interest rate based on the current rates available for debt of similar remaining maturities and collateral terms.

Repurchase agreements  Fair value approximates the carrying value of such liabilities due to their short-term nature.

Junior subordinated debentures  The fair value for subordinated debentures is calculated using discounted cash flows based upon current market spreads to LIBOR for debt of similar remaining maturities and collateral terms.

Off-balance-sheet Instruments (Disclosed at Cost)  Off-balance-sheet instruments are primarily comprised of loan commitments, which are generally priced at market at the time of funding. Fees on commitments to extend credit and stand-by letters of credit are deemed to be immaterial and these instruments are expected to be settled at face value or expire unused. It is impractical to assign any fair value to these instruments. At March 31, 2013, un-funded loan commitments totaled $77.8 million and stand-by letters of credit totaled $1.9 million. At December 31, 2012, un-funded loan commitments totaled $67.8 million and stand-by letters of credit totaled $2.1 million.

ACCUMULATED OTHER COMPREHENSIVE INCOME

NOTE 12:  STOCKHOLDERS’ EQUITY

On January 30, 2009, as part of the Capital Purchase Program ("CPP") of the Emergency Economic Stabilization Act of 2008 administered by the United States Department of the Treasury ("the Treasury"), DNB entered into a Letter Agreement and a Securities Purchase Agreement with the Treasury, pursuant to which the DNB issued and sold on January 30, 2009, and the Treasury purchased for cash on that date (i) 11,750 shares of the Corporation’s Fixed Rate Cumulative Perpetual Preferred Stock, Series 2008A, par value $10.00 per share, having a liquidation preference of $1,000 per share ("the CPP shares"), and (ii) a ten-year warrant to purchase up to 186,311 shares of the DNB’s common stock, $1.00 par value, at an exercise price of $9.46 per share, for an aggregate purchase price of $11,750,000 in cash. This transaction closed on January 30, 2009. The issuance and sale of these securities was a private placement exempt from registration pursuant to Section 4(2) of the Securities Act of 1933. The Bank provided dividends to the Corporation in connection with the $11,750,000 of Fixed Rate Cumulative Perpetual Preferred Stock sold on January 30, 2009 as part of the CPP.

On August 4, 2011, DNB entered into a Securities Purchase Agreement with the Secretary of the Treasury, pursuant to which the Company issued and sold to the Treasury 13,000 shares of its Non-Cumulative Perpetual Preferred Stock, Series 2011A (“Series 2011A Preferred Stock”), having a liquidation preference of $1,000 per share for aggregate proceeds of $13,000,000.   The Securities Purchase Agreement was entered into, and the Series 2011A Preferred Stock was issued, pursuant to the Treasury’s Small Business Lending Fund program (“SBLF”), a $30 billion fund established under the Small Business Jobs Act of 2010, that encourages lending to small businesses by providing capital to qualified community banks with assets of less than $10 billion. Of the $13.0 million in aggregate proceeds, $11,879,000 was used to repurchase all CPP shares ($11,750,000 was paid in principal and $128,900 in accrued, unpaid dividends related to the CPP shares) held by the Treasury as described above. The securities sold in this transaction were exempt from registration under Section 4(2) of the Securities Act of 1933, as amended, as a transaction by DNB not involving a public offering.

The Series 2011A Preferred Stock is entitled to receive non-cumulative dividends payable quarterly, on each January 1, April 1, July 1 and October 1, beginning October 1, 2011.  The dividend rate, which is calculated on the aggregate Liquidation Amount, was initially set at 3.874% per annum, and  was based upon the level of “Qualified Small Business Lending”, or “QSBL” (as defined in the Securities Purchase Agreement) originated by the Company’s wholly owned national bank subsidiary DNB First, N.A. (the “Bank”).  The dividend rate for dividends beyond the initial period are  based upon the “Percentage Change in Qualified Lending” (as defined in the Securities Purchase Agreement) between each dividend period and the “Baseline” QSBL level.  Such dividend rate may vary from 1% per annum to 5% per annum for the second through tenth dividend periods depending on the volume of Qualified Small Business Lending the Bank will originate in future periods, and will be fixed at a rate between 1% per annum to 7% per annum and remain unchanged up to four and one-half years following the funding date (the eleventh through the first half of the nineteenth dividend periods).  Because it is not feasible to predict the volume of Qualified Small Business Lending in future periods, it is not feasible to estimate specific future dividend rates under this formula.  If the Series 2011A Preferred Stock remains outstanding for more than four-and-one-half years, the dividend rate will be fixed at 9%.  Prior to that time, in general, the dividend rate decreases as the level of the Bank’s Qualified Small Business Lending increases.  Such dividends are not cumulative, but the Company may only declare and pay dividends on its common stock (or any other equity securities junior to the Series 2011A Preferred Stock) if it has declared and paid dividends for the current dividend period on the Series 2011A Preferred Stock, and will be subject to other restrictions on its ability to repurchase or redeem common stock and other securities.  In addition, if (i) the Company has not timely declared and paid dividends on the Series 2011A Preferred Stock for six dividend periods or more, whether or not consecutive, and (ii) shares of Series 2011A Preferred Stock with an aggregate liquidation preference of at least $13,000,000 are still outstanding, the Treasury (or any successor holder of Series 2011A Preferred Stock) may designate two additional directors to be elected to the Company’s Board of Directors. DNB paid an annual rate on the $13.0 million of Series 2011A Preferred Stock of 1.00%, 1.00% 1.00%, 3.90% and 3.80% for the quarters ended March 31, 2013, December 31, 2012, September 30, 2012, June 30, 2012 and March 31, 2012, respectively.

As more completely described in the Certificate of Designation, holders of the Series 2011A Preferred Stock have the right to vote as a separate class on certain matters relating to the rights of holders of Series 2011A Preferred Stock and on certain corporate transactions.  Except with respect to such matters and, if applicable, the election of the additional directors described above, the Series 2011A Preferred Stock does not have voting rights.

The Company may redeem the shares of Series 2011A Preferred Stock, in whole or in part, at any time at a redemption price equal to the sum of the Liquidation Amount per share and the per-share amount of any unpaid dividends for the then-current period, subject to any required prior approval by the Company’s primary federal banking regulator.

On September 21, 2011, DNB entered into a letter agreement (the “Warrant Letter Agreement") with the Treasury. Pursuant to the Warrant Letter Agreement, DNB Financial Corporation repurchased from the Treasury the warrant to purchase 186,311 shares of DNB Financial Corporation's common stock issued to Treasury in January 2009 under CPP. DNB Financial Corporation paid a purchase price of $458,000 for the warrant.

Earnings Per Share [Abstract]

EARNINGS PER SHARE

NOTE 6: EARNINGS PER SHARE 

Basic earnings per share (“EPS”) is computed based on the weighted average number of common shares outstanding during the period. Diluted EPS is computed using the treasury stock method and reflects the potential dilution that could occur from the exercise of stock options, and warrants and the amortized portion of unvested stock awards. Stock options and unvested stock awards for which the exercise or the grant price exceeds the average market price over the period have an anti-dilutive effect on EPS and, accordingly, are excluded from the calculation. Treasury shares are not deemed outstanding for calculations. There were no outstanding stock warrants in 2013 and 2012, 128,568 anti-dilutive stock options outstanding, and no anti-dilutive stock awards outstanding at March 31, 2013. There were no anti-dilutive stock warrants outstanding, 148,459 anti-dilutive stock options outstanding, and no anti-dilutive stock awards at March 31, 2012. See Note 9 for a discussion of stock warrants issued and redeemed in conjunction with Preferred shares issued to the U.S. Treasury Department as part of the CPP. The following table sets forth the computation of basic and diluted earnings per share:

The majority of the proceeds of each issuance were invested in DNB’s subsidiary, DNB First, National Association, to increase the Bank’s capital levels. The junior subordinated debentures issued in each case qualify as a component of capital for regulatory purposes. DNB Capital Trust I and II are special purpose Delaware business trusts, which are not consolidated.

DNB Capital Trust I

DNB’s first issuance of junior subordinated debentures was on July 20, 2001. This issuance of debentures are floating rate and were issued to DNB Capital Trust I, a Delaware business trust in which DNB owns all of the common equity. DNB Capital Trust I issued $5.0 million of floating rate (6 month Libor plus 3.75%, with a cap of 12%) capital preferred securities to a qualified institutional buyer. The proceeds of these securities were used by the Trust, along with DNB’s capital contribution, to purchase $5.2 million principal amount of DNB’s floating rate junior subordinated debentures. The preferred securities have been redeemable since July 25, 2006 and must be redeemed upon maturity of the debentures on July 25, 2031.

DNB Capital Trust II

DNB’s second issuance of junior subordinated debentures was on March 30, 2005. This issuance of debentures are floating rate and were issued to DNB Capital Trust II, a Delaware business trust in which DNB owns all of the common equity. DNB Capital Trust II issued $4.0 million of floating rate (the rate was fixed at 6.56% for the first 5 years and is now adjusting at a rate of 3-month LIBOR plus 1.77%) capital preferred securities. The proceeds of these securities were used by the Trust, along with DNB’s capital contribution, to purchase $4.1 million principal amount of DNB’s floating rate junior subordinated debentures. The preferred securities have been redeemable since May 23, 2010. The preferred securities must be redeemed upon maturity of the debentures on May 23, 2035.

Summary of Significant Accounting Policies [Abstract]

Consolidation, Policy [Policy Text Block]

The accompanying unaudited consolidated financial statements of DNB Financial Corporation (referred to herein as the "Corporation" or "DNB") and its subsidiary, DNB First, National Association (the "Bank") have been prepared in accordance with the instructions for Form 10-Q and therefore do not include certain information or footnotes necessary for the presentation of financial condition, statement of operations and statement of cash flows required by generally accepted accounting principles. However, in the opinion of management, the consolidated financial statements reflect all adjustments (which consist of normal recurring adjustments) necessary for a fair presentation of the results for the unaudited periods. Prior amounts not affecting net income are reclassified when necessary to conform to current period classifications. The results of operations for the three months ended March 31, 2013 are not necessarily indicative of the results which may be expected for the entire year.  The consolidated financial statements should be read in conjunction with the Annual Report and report on Form 10-K for the year ended December 31, 2012.

Stockholders' Equity [Abstract]

STOCKHOLDERS' EQUITY

NOTE 12:  STOCKHOLDERS’ EQUITY

On January 30, 2009, as part of the Capital Purchase Program ("CPP") of the Emergency Economic Stabilization Act of 2008 administered by the United States Department of the Treasury ("the Treasury"), DNB entered into a Letter Agreement and a Securities Purchase Agreement with the Treasury, pursuant to which the DNB issued and sold on January 30, 2009, and the Treasury purchased for cash on that date (i) 11,750 shares of the Corporation’s Fixed Rate Cumulative Perpetual Preferred Stock, Series 2008A, par value $10.00 per share, having a liquidation preference of $1,000 per share ("the CPP shares"), and (ii) a ten-year warrant to purchase up to 186,311 shares of the DNB’s common stock, $1.00 par value, at an exercise price of $9.46 per share, for an aggregate purchase price of $11,750,000 in cash. This transaction closed on January 30, 2009. The issuance and sale of these securities was a private placement exempt from registration pursuant to Section 4(2) of the Securities Act of 1933. The Bank provided dividends to the Corporation in connection with the $11,750,000 of Fixed Rate Cumulative Perpetual Preferred Stock sold on January 30, 2009 as part of the CPP.

On August 4, 2011, DNB entered into a Securities Purchase Agreement with the Secretary of the Treasury, pursuant to which the Company issued and sold to the Treasury 13,000 shares of its Non-Cumulative Perpetual Preferred Stock, Series 2011A (“Series 2011A Preferred Stock”), having a liquidation preference of $1,000 per share for aggregate proceeds of $13,000,000.   The Securities Purchase Agreement was entered into, and the Series 2011A Preferred Stock was issued, pursuant to the Treasury’s Small Business Lending Fund program (“SBLF”), a $30 billion fund established under the Small Business Jobs Act of 2010, that encourages lending to small businesses by providing capital to qualified community banks with assets of less than $10 billion. Of the $13.0 million in aggregate proceeds, $11,879,000 was used to repurchase all CPP shares ($11,750,000 was paid in principal and $128,900 in accrued, unpaid dividends related to the CPP shares) held by the Treasury as described above. The securities sold in this transaction were exempt from registration under Section 4(2) of the Securities Act of 1933, as amended, as a transaction by DNB not involving a public offering.

The Series 2011A Preferred Stock is entitled to receive non-cumulative dividends payable quarterly, on each January 1, April 1, July 1 and October 1, beginning October 1, 2011.  The dividend rate, which is calculated on the aggregate Liquidation Amount, was initially set at 3.874% per annum, and  was based upon the level of “Qualified Small Business Lending”, or “QSBL” (as defined in the Securities Purchase Agreement) originated by the Company’s wholly owned national bank subsidiary DNB First, N.A. (the “Bank”).  The dividend rate for dividends beyond the initial period are  based upon the “Percentage Change in Qualified Lending” (as defined in the Securities Purchase Agreement) between each dividend period and the “Baseline” QSBL level.  Such dividend rate may vary from 1% per annum to 5% per annum for the second through tenth dividend periods depending on the volume of Qualified Small Business Lending the Bank will originate in future periods, and will be fixed at a rate between 1% per annum to 7% per annum and remain unchanged up to four and one-half years following the funding date (the eleventh through the first half of the nineteenth dividend periods).  Because it is not feasible to predict the volume of Qualified Small Business Lending in future periods, it is not feasible to estimate specific future dividend rates under this formula.  If the Series 2011A Preferred Stock remains outstanding for more than four-and-one-half years, the dividend rate will be fixed at 9%.  Prior to that time, in general, the dividend rate decreases as the level of the Bank’s Qualified Small Business Lending increases.  Such dividends are not cumulative, but the Company may only declare and pay dividends on its common stock (or any other equity securities junior to the Series 2011A Preferred Stock) if it has declared and paid dividends for the current dividend period on the Series 2011A Preferred Stock, and will be subject to other restrictions on its ability to repurchase or redeem common stock and other securities.  In addition, if (i) the Company has not timely declared and paid dividends on the Series 2011A Preferred Stock for six dividend periods or more, whether or not consecutive, and (ii) shares of Series 2011A Preferred Stock with an aggregate liquidation preference of at least $13,000,000 are still outstanding, the Treasury (or any successor holder of Series 2011A Preferred Stock) may designate two additional directors to be elected to the Company’s Board of Directors. DNB paid an annual rate on the $13.0 million of Series 2011A Preferred Stock of 1.00%, 1.00% 1.00%, 3.90% and 3.80% for the quarters ended March 31, 2013, December 31, 2012, September 30, 2012, June 30, 2012 and March 31, 2012, respectively.

As more completely described in the Certificate of Designation, holders of the Series 2011A Preferred Stock have the right to vote as a separate class on certain matters relating to the rights of holders of Series 2011A Preferred Stock and on certain corporate transactions.  Except with respect to such matters and, if applicable, the election of the additional directors described above, the Series 2011A Preferred Stock does not have voting rights.

The Company may redeem the shares of Series 2011A Preferred Stock, in whole or in part, at any time at a redemption price equal to the sum of the Liquidation Amount per share and the per-share amount of any unpaid dividends for the then-current period, subject to any required prior approval by the Company’s primary federal banking regulator.

On September 21, 2011, DNB entered into a letter agreement (the “Warrant Letter Agreement") with the Treasury. Pursuant to the Warrant Letter Agreement, DNB Financial Corporation repurchased from the Treasury the warrant to purchase 186,311 shares of DNB Financial Corporation's common stock issued to Treasury in January 2009 under CPP. DNB Financial Corporation paid a purchase price of $458,000 for the warrant.
